P1151 code 1998 Mustang GT
I recently bought a 98 Mustang GT 4.6 so far been a ok car. It had 17 codes when first ran, but I knew nothing of them, or how reliable they were so I had it reset then drove it for a while. Got a few new codes and cleared them by changing spark plugs, fuel pump, fuel filter, MAF sensor. Now I'm down to one, still getting a P1151 Lack of 02 switches-bank 2 sensor 1, ECM could not adjust fuel trim because of a lean or rich condition. Thats what the paper says when I had Auto Zone run the codes on it. It also has a very light tapping on passenger side of engine. I'm guessing that a new 02 sensor will fix this problem. Is this your opinion as well and if so which one is it actually? there are 4 sensors on the exhaust.
