Engine Performance problem
2001 Ford Taurus 6 cyl Front Wheel Drive Automatic 116000 miles
Got fault code P1131
Tried cleaning MAF and it didn't work
How do I get to the upstream O2 sensor on bank 1? All of the other sensors (upstream and down) are easy to get to. But of course, the one I need to access appears to very difficult to get to from under the car and from above. I don't know alot about cars, and don't want to have to take too much apart unnecessarily. Any help would be appreciated.
