hey guys, i got a 99 gt that idles really bad, particularly in the mornings. sometimes to the point where it stalls itself out. i was told that it may be IAC valve so i got some carb cleaner and sprayed it out, but it hasnt helped. does it need to be replaced?? will a bad iac hurt my 1/4 times??

If you have to keep your foot on the accelerator just to keep the car idling, then you need to replace the IAC. Cleaning it won't really help, because the valve seems to just wear out (a good way for Ford to continue making $65+ from us every few years).

I also noticed strong fumes when the IAC on my car went bad (sorry, but I don't know exactly why). I wouldn't worry as much about the 1/4 mile times as I would the annoyance of trying to keep the car running!

yes replace it. it wont affect your 1/4 times, but theres more to life than 1/4 mile anyway, theres things called turns.

I had to replace mine at like 50k. We cleaned it first with brake fluid cleaner and within a couple days it was bad again. It was like 90 bucks from the dealership...blah...

Here is a great thread on troubleshooting IAC and TPS which are a common source of idle problems.

HUH?? IAC's affect turns... the iac might be bad yes it's good idea too fix it if it's the problem...

and about turns... what are those... racing to me and maybe too this guy too is lining up and running the quarter... turns is a good way too have your car end up upside down in a ditch in some remote area and getting raped by hillbillys... screw turns i build my cars for the straight line..

i never implied IACs affect turning.

ive done both road and dag racing and ya drag racing is nice, but a true test of drivers skill is turning left and right, downshifting, and braking.
