Its a 71 c10,350 l31 heads, mild cam,hei, no work recently on it and ill check some of the things you guys mentioned. thanks It just got cold and it started doing this. I actually bumped down the fuel pressure from 5.5 to 4.5 and that didn't do anything. I'm just guessing its the choke cause everytime I come to a stop and press on the clutch the idle rises and then ill bump the throttle and it goes down then a few seconds later you can hear it rise again.
