What would cause a rolling idle? After engine is up to temp I get a rolling idle. Is this in the tuning? It seems to roll up and down 50 rpm or so.
I am trying to gather some information so i can raise the issue with my tuner.
A list of mods are in my sig.

IPR duty cycle too high in lower range.

Is this something that can or should be adjusted in tuning or is it the HPOP making more oil pressure that can be utilized.

Needs tuning adjustment. THEN it will work flawlessly.

Exactly what Cody said. The Stealth is causing excessive ICP at idle and the PCM is constantly hunting back and forth to stabilize it. Some minor adjustments to your tuning would quickly resolve that.

Take care. :D

Thanks Bill for reconfirming what Cody had mentioned.
