I'm having an issue where after the car is fully warmed up & I come to a stop light, my RPMs will slowly climb to 2k and stay there.

Other than that issue no idle or driveability issues with the car at all.

Anyone have any suggestions?

 

Have you adjusted the TPS position or the throttle cable position lately?

 

No, I have not, should I?

I recently installed an ACT clutch & flywheel too.

 

Does it happen every now and then? or is this a problem that happens everyday? because every now and then my Evo will do that.

 

Happens all the time, I've only had my car back from the shop for 2 days now.

 

Take it back to the shop that put the clutch and flywheel in and tell them to fix it. If it wasn't doing it before that is.

 

Have you checked the throttle cable. My brother had his twisted under the strut tower bar from working on it and forgot to put it back. The kink caused it to idle really high.

 

Boost leak.

 

i'd hazard a guess that it has something to do with the DBW system.. my friend had issues with his.

 

Maybe a unadjusted clutch pedal? Just a toss in the bucket.

 

Sorry for resurrecting an old thread but this just happened to me after installing new clutch. did you ever fix it? Thanks!
