Rough Idle Hey guys I have a 98 z28. Yesterday I was driving my car and while i was sitting at a light it felt like my car was going to stall out. It was idleing really rough. When I step on the gas the car drives fine. It seems like theres something wrong with it getting fuel at idle speed. I have long tube headers on it with an offroad y-pipe. It has o2 sims on it. I havent changed my fuel filter in a couple years. It feels like its going to die on me if i dont keep giving it gas. I was wondering if it could be my 02 sensors or my fuel filter. I have plenty of voltage. Any ideas would be very helpful.

chec your sims to make sure they are still plugged in. then check to make sure all the plugs under your hood are plugged in.. one may have wiggled out.

put a new fuel filter in, pcv valve, and IAT sensor. Still doing it. Fuel pressure is fine. Plugs and wires good. Can't find any vacuum leaks. Is the IAC valve a common thing to go out. I only have 80,000 miles on the car.
