can idle be adjusted , mine is at 500rpms at rest it just don't sound or feel right?
anyone adjusted theres ?

 

like 700 maybe once its warmed up. i dont think it can be adjusted unless you have a tuner.

 

Manual and auto idle at different speeds. My manual runs about 700.
Idle speed is controlled by the PCM.
Try removing the battery cable for a few minutes , 15-20 , then after restart don't touch the gas pedal , just let it relearn its idle setting.

 

700 on my 4.0 and you can adjust it with a tuner
