So my engine started running really rough, like barley chugging along. Pulled over pulled codes. Said it was misfire. I got the plugs, wires and coil pack replaced. I also did idle air control because of codes as well. But anyways, I replaced all of that and still have a cylinder 1 and 3 misfire. I myself am stumped and even have my mechanic stumped as well. HELP!!! PLEASE!!!
