[DML] Re: Another... Cold Start Problem

[Shannon Yocom <ssdelorean@xxxxxxxxx>]

Harold, 
Thanks, I will check those wires and switch.

David T, 
I get the same problem with no humidity or high humidity. It really depends on
how long the car has sat without being ran. I know I need a possible valve
adjustment on the 4,5,6 side. Checking the plugs for wear is on my to-do list.
They were installed last May and have just under 17k miles on them along with the
wires, cap, rotor & O2 sensor. Air filter was changed just before Pigeon Forge.

Sounds like the thermo-time switch mounted on the waterpump is not functioning
or, the wires are not connected well at the switch. Since the wire switch thing
worked for you the cold-start valve is apparently working ok.

Was the humidity really high? It sounds like you need a tune-up replacing the
cap, rotor, ignition wires, and spark plugs. Under high humidity conditions the
secondary ignition system breaks down and the spark doesn't get to the worn spark
plugs. Once you get the motor a little warm it is fine. To complete the tune-up
you should also replace the air filter, the O2 sensor, clean the fuel injectors,
and adjust the valves. You should make sure all the engine systems are
functioning, check the timing, and no vacuum leaks. Don't touch the mixture
screw. If it was properly set in the first place it should not need to be
touched.
