its back in the shop

[KENDO & MYRA]

my cars back in the shop,it stalls when i come to a light,also if your parked and i give it gas and then take my foot off the gas pedal it will stall instead of idle,i tried cleaning the idle air bypass valve but that did not work ,so its in the shop,i should get it back on monday to see whats up,when i left he was running the computer codes

[pro-five-oh]

Tell us what codes he gets. The IAC valve probably needs replacement...its too far gone to be cleaned.

[KENDO & MYRA]

thanks pro,i told the guy that but he said to put the part back in and bring the car to him,it might not be it,but ill bet it is,ill tell you whats up tomorrow

Damn, so close, my money is on either a vacuum leak or that idle valve is bad.

So how much money have you spent on this car? Well its less than a new car payment tho right?! :)

I am going along with you guys on this one.

You know your stuff man, let's hope your mechanic knows better than to mess with ya. ;)

if it doesn't throw any codes, I still say the IAC is bad.

[KENDO & MYRA]

just as i thought,its the iac valve,next time i wont second quess myself

good thing to check the IAC. mine idles funny sometimes , but no codes. im going check this out or get a new one.

[KENDO & MYRA]

a new one is 47.00 money well spent...............

Usually not even worth the effort in cleaning them just to find out it didnt help. Tried to clean mine and ruined it!

Its worth it on a V6 Conti or a 5.0...but yeah, I cleaned the one on my former 4.6L town car, spend an hour removing crap to get to it, and two weeks later had to do it all over again to put a new one in. Sheesh.

Good job Ken, you know your stuff. :)

some of the 3.8 IAC's are not cleanable... but for the low cost, its almost worth just a 'shotgun' it and toss in a new one.
