my idle is a lil rough. well, not really rough just varying. it will drop 100-200 rpms, then back up. no shake, good icp. no codes. any ideas? bad fuel? idk. i doubt bad fuel. i tried shell (what i usually run), Bull Pi$$ (BP), and farm fuel (of course i only run that on the farm wink wink. never had injector trouble, and holding 60 psi fuel pressure at idle.

 

Warm or cold?...

 

Ask TJ, I seem to remember something about the range selector switch on the side of the tranny causing rough idle. Just a W.A.G. Do you have a HPX? It smoohted out my idle and from what I here alot of others too.
