These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1Original post

I've been running the GT3 throttle body along with the IPD plenum for a few years now without issues. I had my AOS go out on the freeway and I was able to drive it just long enough to exit and get her parked. Ever since my AOS went out I've been having strange idle issues. Installed the new AOS and cleaned everything out. Issue 1: At start up after driving it will lag or stall. I will hit the pedal and it wont rev correctly. Then it "clears" and drives fine. Issue 2: At idle the rpm gauge will bounce between 1-200 rpms. Almost sounds like I have a cam. I cleaned the throttle body and replaced my EVO airfilter with my spare. Is there anywhere else I should look? Vacuum leak? Does this engine have an Idle Air Control Valve or Throttle Position Sensor?? Is there a way I can test (ohm meter) to see if the throttle body is still good? Should I open the side of the throttle body and clean out the electronics and re grease? Can my underdrive pulley add to the weird idle? Thank you!

POST 2Original post

You might want to take off the rubber intake hose and examine the inside of your throttle body and air intake tubing for oil. If you had AOS issues, you might not have noticed at first, on down shifting, the air flow goes backwards to a certain degree. Oil may have gotten on your air/mass/flow sensor. Please see thread "Please help cleaning the MAF sensor , post #9 from Intubator. That should help.

POST 3Original post

Screams vacuum leak, so a couple thoughts: a. Remove TB and clean with TB cleaner. If the AOS barfed some gunk into it before it died you could have oil turds now. b. Check for leaks where the rigid vacuum line from the AOS connects to the IPD TB, as it is easy to not reset fully. c. Check the other rigid line end for the aluminum end cap . d. Consider cleaning the MAF. Let us know what works.

POST 5Original post

When you go with the IPD plenum , one of the hoses from the AOS is blocked off that used to connect to the stock plenum. Has the "cork" fallen out of that hose? That could be causing a vacuum issue if it did.

POST 6Original post

Cleaned everything and it was a bad MAF. Replaced and cleared codes. She runs great.
