So me and my buddy have spent about 3 days trying to figure out my misfire issue in my ‘97 Chevy Camaro base with a 3.8L v6. This misfire happened at first right after I washed my car for a short period of time but 3 days ago it started doing it every time the car is started and running. It stutters in idle. And has absolutely no power. We replaced the icm(code reader said multiple misfires), we replaced the cam shaft position sensor(also due to a code). We are getting 45 psi of fuel pressure. It’s getting air and the plugs and plug wires are brand new and all make spark. Right now the only code I am getting is an ignition control system code.
