Black/Blue- 94 Camaro Z28
Misfires when engine warms up... help!!!
i have a 94 Z28 with the lt1 in it. it runs really good when the motor is cold but after about 5 or 10 minutes, it misfires badly and shoots raw fuel out of the exhaust. i put a new optispark in it, new plugs and wires, new o2 sensors, and new fuel injectors. the mods i have are a mac cat back, hooker headers, grenatelli maf, k&n intake, trick flow elbow, and a shift kit. it ran fine before then oneday, it started doin this. anyone ever had this problem or knows anything about this??? please help me out
