Engine Performance problem
2001 Oldsmobile Aurora V8 Two Wheel Drive Automatic 75000 miles
My check engine light came on and had an Auto Zone employee put a computer on my car to see what caused the light to come on, it read O2 sensor issue. I replaced 2 sensors, and still have problems, I went back to Auto zone and he now tells me I have 3 to 4 O2 sensors, can you tell me how many and where they are. I also now get other readings that saya MAP sensor, MAf sensor, Pedal Throttle Position sensor, and Knock sensor. It is driving a little better, but feels like the throttle is stuck open when driving down the highway.
