Car kinda wants to die first crank after sitting for a long time

Fox Body · 04-25-2003, 10:01 AM

Okay, no real biggy, but the 92 GT 5.0 manual, if sitting overnight or for 10hrs or more, if I crank it, it cranks find then idle drops and is about to cut off if I don't give it a small amount of gas, then it idles just fine. Second crank it does fine. Never cuts off. (Nontheless, I dont' think it shoudl cut off in such timid conditions for a car) It has once or twice. Now, this is after sitting (usually overnight and cold outside). Does this seem like perhaps spark plugs need to be changed? I am gonna do that this weekend, b/c I think the time is due. I just got the car a couple of months ago and don't know when the last time they were changed. I'm gonna also change cap and rotor. Anyone else have a problem like this and any other ideas?

Yep, it happens to my '88 all the time except that once it's warmed up and I shut it off quick to run into a store and come back out and start it, it won't idle right if I don't give it some gas quick.
I guess the only way we are going to find out for sure is to pull some codes from the EEC.
