[DML] An odd problem just cropped up.

["Brandon" <morpheus34711@xxxxxxxxx>]

On Sunday, (the day after our Central FL meet here in Orlando) a few
things were done on my car, #4205, including a fuel filter change and
a complete replacement of my melted fusebox and replacing most all of
my relays and circuit breakers, including my RPM relay.  After stage 1
was done, (fusebox and fuel filter) the car eventually started up and
ran  once the fuel system pressurized.  After this, we shut the car
off again and worked on replacing the relays and breakers.  When
finished with this, we fired up the car again and it seemed to be
idling a little rough.  We figured the ECU needed to re-learn
everything so we let it run.  It leveled out, but when I took it for a
drive up to the local Sonic, it was hesitating on acceleration, almost
like it was being starved for fuel or running lean.  

We got it back to my place and hooked up the dwell meter. (I had just
adjusted my mixture the day before and it was good before this) I
started the car, and the needle moved almost all the way over to the
right then gradually crept back down to 0.  Curious, I hooked it up to
#6720, parked right next to mine and it worked fine.  Bamboozled by
this, I started trying to adjust the mixture my feel.  I enriched it,
leaned it out, then slowly richened it till the idle smoothed out. 
Mind you, the frequency valve is silent through all of this.  I
swapped out my new Lambda relay with 6720, and his car ran fine with
both.  My main question is: What does that diag plug connection for
the dwell meter (Top right pin when looking at it from the driver's
side)get it's signal from?  What could have caused this issue?  

I took the car out again last night, and had the same lack of power
issue while the car was warming up... once it did, things seemed to be
ok power wise.  When it started up, it was sputtering a little as
well.  Any information or ideas would be helpful at this point, since
this issue makes absolutely no sense to me.  Thanks in advance for
your help!

Sincerely,
