maybe its 1000 - 1500 only does it in nutural and park and drive when at idle runs and drives great doesnt overheat has 154,000 miles i really need some help please i have 3 kids i changed the iac already but nothing changed!!
check your codes.tps maybe?
If you have a check engine light on, and it's a code for the idle control system, then you may need to repair or replace your engine computer. Because sometimes when the iac goes out, it fries a chip on the computer board. This is especially likely if you had noticed an electrical burning smell in the car when you first started having problems with the idle.
