2) distributor d whole set
3) high tension wire

Try running some seafoam thought the brake booster line and see what it does..Every time i get a car that idles weird i clean the iacv and run some seafoam the the brake booster line and the tank and it usually fixes it.Try that and see what it does.

Here is another one i hate ppl trying to start shit on here. I am tyring to help this guy out and you obviously dont even no what i am talking about so dont post something unless you no what your saying you just make yourself look dumb...... I will put this in step by step instructions for those who dont no and no this has nothing to do with brakes i said the brake booster line which is the main vacuum line that comes from the intake manifold.
1. warm your car up to temp
2.disconnect the brake booster line from the brake booster
3.get somebody to set in the car and give it a little gas as you slowly poor in a third of the seafoam can.
4.reconect the brakebooster line.Then you can either rev your car for a little or drive around.I usually drive around just make sure your not around any cops beceaus your car will be smoking like crazy.

lol so your solution to the problem is to drown the car in seafoam? And your making a statement about how people are dumb? :roll::lame:no: Seafoam is not the correct fix to this guys problem.

Annnnyyyyyyways i think it's sensor related. Maybe a retarded tps sensor. I would start checking voltage to see if any are out of their operating range.
