My GSR is idling at about 1500 rpm's now with my new skunk2 intake manifold. I followed the books procedure on how to adjust the idle and I did just that and 1500 is the lowest I can get it! The screw on the throttle body is turned ALL the way in. I don't know what else to do , the throttle cable is adjusted and everything is adjusted but it still idles way 2 high. What is everyone else doing? Im using the stock GSR throttle cable/bracket and throttle body.

 

u have to be doign something wrong cause i have that manifold and mine ideals fine... and i still using the stock throttle body and cable, but using a type R bracket.

 

what am I doing wrong? I got rid of all that IAB junk and vacuum lines. I checked all the vacuum lines and there perfect.

 

your trubo right? what enigine mangement are u using, cause i unplugged one of my sensors when i went trubo this weekened on my car to get ride of a high and lupe idle

 

Yes its turbo'd. The only sensor I got rid of was the IAB selenoid sensor in that black vacuum tank. No CEL's. A local perforamance shop told me to take off the throttle body and remove the spring pulley and adjust the non-adjusting stop screw. I'll try that and im sure it won't work so i don't know what else to do.

I know many people have this same problem, what did you guys do?

 

Did you bleed the coolant system? Maybe your IAC valve?

 

check your sensors and make sure there in the right place....and switch them and see...that was the problem i had.

 

So, this is when the engine is warm?

I assume that you are using uberdata for engine management, correct? In that case, the engine will idle in a strange manner where the idle bounces between 1500 and 2000 rpms when cold and then when warm, it will idle around 1100 when the car is put into neutral and then slowly go down to 750 rpms. If you notice this, it is completely normal.

If it doesn't do this, there may be a vacuum leak. Did you change the manifold gasket before you put it on?

 

^ never thought about the uberdata factor. that could be it also. Shmoo, :thumbup:

 

Yes I re-used the intake manifold gasket as it was 2 weeks old and pefect shape. Yes im using uberdata. And it bounces around when cold and when the engineis fully warmed. It never did this before I installed the skunk2 manifold so it has somthing to do with that. All my vacuum lines are pefect and triple checked. I have no CEL's. I also thourughly cleaned the IACV and I just bled the coolant by letting it warm up without the rad. cap. I don't know what to do about the bouncing, but Im gonna try and adjust the set screw to stop idle ont he t.b.
