Hey all, I keep getting a 171 code. All I have been told is that it is the o2 sensor, no one can tell my how to check to determine which one. I looked at the MAF. It looks as though one of the filimints in it is toast. When the car is started cold you can't rev up the engine, it will kill it. It has to be running for a minute. When at a stop in gear the engine revs up and down, but much more so with the A/C on. Often when starting out from a stop it will die.\
Thanks for the help.
