Thread: IAC

going to clean my IAC where is it located on a 04 grand prix??

Canadians with 04+ GPs don't have them

sprayed a lot of throttlebody cleaner inside still running like crap could the MAF sensor be bad ?

ok will try tomorrow morning every morning when I start my car it revs up and down for a minute then runs normal ?

Did you actually take the TB off to clean it?....if not you might want to do that

no I haven't is it hard at all ??

Edit: of course that's after you remove the maf and whatever intake setup you have

Yep just like that
Scrub it clean with some rags and TB spray
And get some MAF spray since it will be off...but don't scrub on the MAF

thanks guys got it off now time to clean it

Next step is what FFDP said

Crap it's deeper than a idling problem right?

So it stumbles through the power band or just at 2k?...fuel filter maybe
When was the last time you changed plugs/wires...
Did you scan it to see if there is any codes.

Run a can of seafoam in the tank...maybe dirty injector....start with the simple....do a close visual inspection of vac lines, wiggle spark plug wires to make sure they are on tight,cus it out

I did the plug and wires last summer but put a crap ton of miles on it when I started work and starts at 2k all the way up till the cutoff don't remember when I did the fuel filter

I will get a can of seafoam tomorrow morning and try that

Is this where the iac is located ?

That's your evap solenoid bro, as they said, you don't have an IAC on your car.

The car uses the throttle body to keep the engine idling.
