110429, Modern 60mm - Idle Issues
Posted by teklein, Oct-28-08 12:43 PM
Hey!

I got the Modern on, and it pulls awesome, I dont think this car has ever felt that strong to 7k.

Anyways, whats everyones secrets for the IAC?

Im gonna pull it apart tomorrow and pull the tip out, then put it back together and see if I can get it to idle below 2K!

I reset the computer as well. Didnt mess with it from the stock TB to the new one. Idled at 850 with the stocker, I would have though the IAC wouldnt need need to readjust itself with the new one.

Guess it does!

Secrets, lol? It should be plug and play, mess with the screw to make sure the butterfly is closed all the way.

The iac should reset itself as soon as you turn the car off

Vac leak. Nothing to do with the IAC. The MP 60mm throttle body IAC cavity are milled to the same size and standard as the stocker.

Yeah, you have a vac leak and a pretty big one OR the TPS is not on correctly. Make sure the TPS is on the shaft correctly and the ECU doesnt think the plates are open. Loosen the adjusting screw on the TB itself. That will ensure the plates are fully closed.

Didnt even think of the TPS...

Looking at the TPS side, I cocked the sensor to the left, then moved it to the right to bolt it on. Thats how I have always done it :shrug Should it be cocked to the right and slid to the left?
Actually, as I was typing that, I dont think it can be cocked to the right then slid to the left...

The throttle stop screw is not even touching the lever at this point.

Weird thing that I have had almost the EXACT same issues with my Jeep TB, but the Jeep TB works fine on Mikeys car. The only TB I have ever gotten to work right is my stocker.

As far as vac leaks, I was spraying carb cleaner around around everything, throttle never flinched, just stayed at 2k.
