Hello to all.
currently i have a 96 cavalier 2.2l. At this time, the car is riding very rough. recently, i took the car to have it scanned, and most of the codes that came up, i already had them replaced maybe about 6 months ago. I have replaced my IAT, TPS, MAP, and both o2 sensors. Besides the sensors, now a emissions control, and a cylinder 3 misfire has come up. What about replacing the EGR valve? Guys please help me out. I called the chevy dealer, and i'm thinking about getting a new PCM. Will a new PCM solve all of my problems?
P1080 MAP High Input, O2 heater, Emission control(dont say) TPS High and low inputs, IAT sensors. Also have low compression, and a hissing sound is coming from the engine.
Before spending any more $ solve the hissing sound, probably a lose vaccum line or broken vaccum hose it may solve the codes.
