EGR Valve / ECM / ECU - NOTHING IS WORKING RIGHT!
Ok guys, I've got several questions:
1. What are the symptoms of a bad EGR Valve? Is it easy to replace?
2. Whats the difference between an ECM and a ECU? Does anyone know where I can get a replacement ECM?
3. My car is running VERY rich! Lots of thick exhaust and smells bad too. Also the check engine light comes on (even after replacing the O2 sensor and resetting the computer). The car is also boggling down, probably has something to do with the check engine light/rich exhaust?? BTW, I've also replaced the Throttle Positioning Sensor (TPS).
Any suggestions or help would be greatly appreciated.
Thanks,
Essa
