Re: 1987 Ford Tempo with high idle in P when warm
Okay, so the new injector did not fix the problem. The mechanic did not remove and test the idle air control motor so I don't if it could still be the problem or not.
He thinks it's all related to the negative battery cable that needs replacing because of all the codes the computer is throwing and all the weird things my car is doing now that the vacuum lines and other things are back to where they are supposed to be. So they are replacing the battery cables today. The negative one is quite long and connects to the computer module.
How many of you have had luck with idle issues being fixed with replacing the idle air control motor? Is it hard to replace? Does it matter which brand of replacement part I buy?
I'm frustrated that I'm sinking all this money into this car and it's getting worse, not better.
