Re: iac attack
personally, I'd only use the original delco / delphi part. I've had issues with aftermarket sensor / engine control electronics

Re: iac attack
thank you for the reply,
as far as brands go i could only get duralast pn# ac114. on my old one it had a "B" stamped on it. the new one had a "C" stamped on it.

Re: iac attack
I got the Standard Controls IAC from Tucker and i swapped it back to back with my oem and noticed no difference.
The key, like Mike said, is making sure its been preset properly.
Then resetting the IAC stepping by jumping the aldl terminals after its been installed in the TB.
PCV matters because they are designed to work with a boosted application.
that's why you have 2.
one for under vacuum, the other for under boost conditions.

Re: iac attack
again, thanx for your replies.
i read somewhere that you can adjust them by screwing them in. i tried that on the old one and got nowhere. i also tried to push in the old pintle and that went nowhere. i didn't try the new one because i didn't want to screw it up before i got to use it.
i installed the new one and even reset the computer by disconnecting the bat. for a while just because i thought that i should for good measures. :dunno: went on a test run and cruising speed was fine/normal. started to boost and a huge stall happened. it wasn't even a huge boost either. it was gradual. continued to drive around and it didn't do it at the same speed. could it have reset/corrected itself? still have yet to try it at wot or do i still need to take it back out and measure the pintle to mounting surface and make sure it's under the 28mm mark as it was stated in the book by sy2932. which by the way i really appreciate.
this is been an ongoing bug that i've been dealing with for the past month or so. the iac was the last component that needed to be replaced since my purchase back in april '08.

Re: iac attack
To set the iac initially you have to hold the spring back with your finger and screw or unscrew the pintle to the desired measurement.
The spring has a notch in it that prevents the pintle from spinning.
I match the new IAC sensor to the old on the bench then install, reset aldl, clear ecm and go with it.
