After squeezing yesterday, my car started idling rough, like I have a mean Cam in or something. What could be wrong? It doesn't die or anything, I have no power loss, but just when I am sitting still the car feels like a Modded V8. Should I just reset my ECU and see waht happens? TIA

First off, do a compression test to rule out a blown motor or head gasket. Check you plugs to be sure they aren't fouled and whatnot..I would check those things first...then get back to us..

Ok guys, I changed my plugs and wires yesterday. Nothing has changed, still a rough idle when at a stop light or something. Would I have any power loss with a blown headgasket? Cause I still have all the power. Could it be my timing belt by any chance? TIA

make sure all ur vac lines are still secure. the other day i took off the pcv line and the car idled extremely rough, the engine was "jumping" all over the place.

It actually sounds like you burnt one of your intake valves. I have seen the same thing on a buddy's car after he sprayed. Just my two cents. I would definitely do a compression test.

Check your plugs man. Probably fouled one and its causing your rough idle.
