RPM's bouncing after warm up
Hey how's it going everyone hope you all can help me
So here the deal i have a 94 civic dx with a mini-me swap and just recently the rpm's started bouncing after the car warms up and i stop at a light or am parking. The check engine light isn't on nor is it throwing a code. I cleaned the IACV still bounced so i got another one from the junkyard and cleaned it to there was no change. I also changed out the FITV from a junkyard it looked cleaner then the one that was on my car thinking that would help but still no change. I haven't had the chance to burp the coolant to see if thats the problem or not but will try on my weekend.
I'm starting to run out of idea's and am half temped to go buy all new vacuum lines from AutoZone only because the cars 17 years old

Re: RPM's bouncing after warm up
I'd definitely try bleeding the cooling system next. When my engine was doing this it went away for a few weeks after a bleed but starting bouncing again, ultimately turned out to be a blown head gasket causing air pockets.
