Subject: Re: Starting and low idle
I drove the car just about all day and noticed that the probelm was really
the starting but that it would struggle to stay running, the idle seem to be to
low. other times it worked fine. I must have started the car over 15 times
today (a lot of driving) and only had it act up twice. once when it needed me to
pump the gas which then the car would jerk after i put it in gear like it was
going to stall unless i pumped the gas more. The other two times it would just
need my help to get to a high idle, if i pumped the gas after it started so
it wouldn't stall. But after a few mins I ran just fine.

Subject: RE: HIGH IDLE
John, I know this is late, but fuel lines very seldom stop up. They are not
rubber. The injector has a filter in it that I can normally clean out with
the heated ultrasonic cleaner and the output port on the fuel distributor
has a filter basket in it also that can be cleaned or taken out. A vacuum
leak can cause the high idle or the idle speed sensor.

Subject: RE: Starting and low idle
Darryl, Read the plugs, if it's starting ok but having a hard time running
then you may have a fuel dumping problem. Take out a plug and go to the plug
cart on the web site to see the condition. If the car is flooding they
should be black. There are several things that could cause this. Warm up
regulator/Control pressure regulator, Idle speed motor
not opening, idle speed micro switch not working, vacuum problems, control
plunger out of adjustment and more.

It is best to use a vacuum gauge. CFM is irrelavent. Get vacuum to

Subject: Re: vacuum problem analysis please!
You keep coming back to the vacuum advance. Just put a vacuum source
on it and see if it moves. Measure for vacuum before and after the
electric valve. Having it connected in reverse causes the vacuum
advance to stay "stuck" in advance as the vacuum isn't dumped. Make
sure the mechanical advance is not stuck. If your eyes are burning
from the exhaust it IS running too rich. The causes include a mixture
screw way out of adjustment, a dirty injector, a misfiring cylinder, a
leaking cold start valve.

Subject: RE: vacuum problem analysis please!
Andy, I cut out a lot of the message to get to the question. Is the enging
hot or cold while performing the test. Also, you can bypass the vacuum
solenoid and go straight to the ignition and see if you have the same
results.
The green air pivot switch or vacuum swithch works off the hot or cold water
in the internal water pipe. When the coolant is cold the vacuum is routed to
the WUR and the vacuum is shut off to the solenoid for the ignition
distributor advance. After the coolant heats up, the valve closes the vacuum
to the WUR and then is directed to the vacuum solenoid for the ignition
distributor. But, If the car is at idle and the micro switch is tripped and
is working, then the vacuum solenoid is electrically shuts off vacuum to
the ignition distributor to advance the timing untill the idle speed
microswitch is dis engauged.
The other problem with the fuel seems to be the WUR allowing the control
plunger in the FD to rise to high creating and enrichment or there is a
vacuum leak which I know you would have checked.

Subject: [DML] vacuum problem analysis please!
F). HOWEVER, when i replace that hose onto the advance diaphragm, i can
feel
that there is vacuum on it (there shouldn't be) and it then shoots up the
advance on the timing. now with the timing wheel on my light at 0 (not
showing
advance) i can see the timing mark way up at like 50 deg BTC. at this
point, the
car runs smoother and better (when advanced and at idle).
3) started inspecting WHY there is vacuum to the diaphragm when the car is
hot. checked the idle speed switch. with a meter, i verified that with the
car
not running, the switch does indeed function when activated (checked ohms).
4) started the engine and with it running and at idle, checked the voltage
at
the electrical connector on the side of the advance solenoid. got a
definite
14.5 volts. this should indicate that the idle speed switch is working
correctly and it is tripped at the proper times. this should also indicate
that
the advance solenoid, if it is not broken, should be energizing AND should
not
allow vacuum to the distributer advance diaphragm. yet it DOES!
what has me puzzled is that this would tend to indicate a broken advance
solenoid. however i replaced this part this summer already (and perhaps i
was the
one who routed those hoses backwards when installing it). i suppose i COULD
have a defective part, but i got it from Grady and it wasn't a used part.
also note that when the car is running, it tends to smooth out for a bit,
then begin to surge a little, then smooth out, etc. the exhaust is very
rich,
too. sometimes when working over the engine it is enough to make your eyes
water a little.
what else should i check in order to rule out other possibilities? the only
conclusion i can come to is that the advance solenoid is broken, but it's
hard
to believe since it is a pretty new part. any other ideas? other tests of
other parts to do? certainly the problem (or at least A problem) is the
presense of vacuum at the diaphragm even when the solenoid is receiving
14.5V from
the idle microswitch. what else could be at fault?
I am at a loss and would like to continue working on this over the weekend,
so if you have a response, please CC it to my actual email address as well
as
to the list so i can get it right away.
Thanks in "advance" (heh heh)

And you would be wrong. Age does deteriorate tires.
The rubber compounds outgas from the moment they
are released from the mold. You can vacuum pack
a fresh tire, stuff it in a barrel, stuff the
barrel in a climate controlled room, turn out
the lights and lock the door and after 10 years
the tire is still junk. The tread will harden,
the sidewalls will stiffen, and the tire will
lose grip and stability. All those sprays do
NOTHING to preserve a tire because they can't
stop the chemistry. If they did, you would have
to coat the whole tire inside and out, not just
the part you can see.
If you just want something to hold the car up
and look pretty, go ahead and spray up your old
tires. If you want to experience the car as the
designers intended, you need new tires.

Subject: Re: delorean air conditioning question
You need to pull a vacuum of 700 microns minimum. You cannot read this
on an ordinary compound gauge, you need an electronic vacuum gauge.
You should hold this level for at least 1/2 hour, the longer and lower
the better. I try for 400 microns for 1 hour. If you can't get there
it could mean either leaks, contamination, or too much moisture in the
accumulater. CFM is short for Cubic Feet per Minute which is a
measurement of flow, not pressure-vacuum. You can't damage the seals
from too much vacuum. In reality it is just the removal of atmospheric
pressure which is around 15 psi so you can think of it as a negative
15 psi pressure. If any seals do fail during an evacuation they
wouldn't have held up against the pressure which on the low side can
go over 100 psi and on the high side over 150 psi.

Follow the wiring harness and clean all the plugs and any wires you

a wiring diaghram and follow the problem to it's source. You don't

With equipment normally available you can't pull too much vacuum.
However, you need to pull close to 20 inches to get all the moisture

Subject: Re: vacuum problem analysis please!
List,
with a listmember's help i was able to find the source of my problems. one
of the wires on the back of the microswitch wasn't very tight and wasn't giving
a constant power source. now that i cut the wires and recrimped them, the
vacuum goes away when the engine gets hot like it should. now i no longer have
advance at idle. base timing was also about 4 deg off, which i have corrected.
now i am positive my advance system and microswitch works the way it should
and my timing is perfect.
however now that everything is set right, i have a couple more collateral
problems:
1). when you give it some gas and let it come back down to idle, it idles at
about 1000RPM.? that's too high.? it is smooth but won't go all the way back
down.? if i let it run at 1000 for about a minute it actually drops back down
on its own sometimes.? what is causing this? i am 100% positive that the idle
microswitch works and switches as it should....
2).? i think the stop screw on the throttle hammer (the piece that trips the
microswitch) -? is not set right anymore.? i unscrewed it to see if it would
drop the idle a little (i messed with it last year too so i wondered if it was
set right anymore) but it didn't help any.? actually i know it shouldn't since
idle is electronically controlled but maybe it was WAY off... how do i set
that stop screw (the lower one - not the one that hits the switch) against the
brass stop piece so it is adjusted right? if it is down too far, the throttle
plates are cracked open, so where is the right point to screw it in? either
way, right now it still trips my microswitch. i just want the throttle plates
open however much they should be at idle.
all tests are being done with the engine at operating temp. i can hear my
idle speed motor buzzing too.
any tips are appreciated - please CC to my personal email so i can keep
working over the weekend.

It may be of note to know that the vast majority of these cars have $10K sunk
into the body kits, wheels, tires, stereo, and tinting. at car shows i very
rarely see one that actually has any engine modifications besides your typical
cold-air intake, and a free-flow exhaust. it is also of note to see that this
year's Honda Civic puts out at best 127hp with the most powerful engine
option. with all those wings and body kits, surely the car weighs more now than it
did stock (slower too).
in fact, where i work i see cars like this all the time and usually they put
most of their money on purple and yellow wiring looms/conduit, billet oil
caps, and stainless braided radiator hoses. usually the engines and transmissions
leaks copious amounts of fluid, not to mention most of the lowered ones have
dented transmission pans or frames. oh yeah - almost every one of them has
the Check Engine light illuminated.
all show, no go - but then i suppose some would say that about the DeLorean
too?
I would like to put the 3.0L quad cam motor from my 94 Lexus ES300 in a
DeLorean. about 197hp with lots of pull - even on the interstate at 85mph.

The entire job, start to finish. You deliver them a DeLorean, they give

The Northstar conversion is a professional job that you don't have to

more than the car, but you can't underestimate the amount of trouble you
will get yourself into doing an engine swap. It always costs more and
takes longer than you think.
Also, my take on the transmission issue, is that when it comes to breaking
transmissions, driving style matters a lot more than the amount of power
you put in the transmission. If you're gentle, don't speed shift or drop
the clutch, the transmission will hold up to a lot more power. And even
then, torque matters a lot more than HP. If your motor is a big torque
monster like a smallblock V8, you need a tougher transmission than if it
is a high-revving motor with most of the power up high. The Northstar,
despite being a V8, is still fairly gentle on the parts.

Look at the top of a DeLorean distributor cap - the sparks (and
therefore pistons) are not distributed 60 degrees apart.

With odd fire, the cylinders fire in pairs, the two cylinders in the same
"length-wise" position firing in rapid succession, then a pause, then two
more, then another pause, then the last two. With even fire, the
cylinders all fire individually and are distributed around the engine in
an order which minimizes vibration and noise.
Generally odd-fire engines have more low-end torque, but even-fire engines
run more smoothly. There's a big difference in the sound and feel, but
not that much in the performance.
There are a lot more even fire engines around because most people value
noise and smoothness over torque, but odd fire engines are still popular
in places- the Viper uses an odd fire engine (but of course with five
groups of cylinders instead of three :) )

Subject: Re: Bad Experience with Original Tires
Since the age question on original DeLorean tires has come up. I would like
to share my personal experience with the group. I bought my DeLorean (#5830) in
1989 from the original owner with 13,000 miles on it. The car had always been
stored indoors and only driven occasionally. The original tires were still on
the car and they looked brand new. In December 1992 (mileage was 16,000+) my
wife was driving the DeLorean on I-295 in Jacksonville, Florida at about 65
mph. Suddenly and without warning, the left rear tire blew out. Fortunately, she
was able to maintain control of the vehicle and bring it to a safe stop on
the shoulder of the highway. I happened to be following her at the time in
another vehicle and saw the tire blow. Examination of the tire disclosed that a
sizable portion of the outside sidewall had blown out of the tire.
Since the tire blew for no apparent reason, I contacted Goodyear and
eventually spoke with someone in their engineering department. I was told even though
the tires had very little tread wear, they were eleven years old at the time
of the failure, and that time takes its toll on tire composition. I was also
told that exposure to light hastens the deterioration of the tire material, but
in no case would he recommend using tires over ten years old on any vehicle
that is driven at highway speeds.
I replaced the original tires with Goodyear Aquatreads in 1992. I now have
21,000 miles on these tires, and I plan to replace them in the near future.
