ya'll havin a problem with your idle raising by itself?
after i drive for a while ( 30min to work) when i sit at a redlight my idle creeps up to like 1200-1300rpm, and in between shifts it'll raise to about the same...doesnt do it all the time though.

Only mods are:

c&l maf meter and tube
mac catted prochamber with single chamber flowmasters.

I hear alot of people talking about the IAC valve with hanging RPM's I believe. Maybe it's that. I've got the C@L system also and mine runs perfect. I've never had any problems with hanging or raising RPM's.

Mine did that once. It kinda freaked me out at the time but it never did it again and I forgot about it.

have the carbon cleaned off the iac or do it yourself. My idle vary about 200-300 rpm from time to time, cleaned the IAC and no more variance.
