P0131 and P0151 trouble
I have a 97 GMC Jimmy. I am getting a P0131 code all the time and a P0151 sometimes. I replace the Bank 1 sensor 1 in January and had no problem all summer. Now out of nowhere, i am getting the code again and having driving issues. First thing in the morning, I can drive about 10 mile and then the truck starts bucking and I lose power up hills or on take offs from a stop or passing. If I give it a slow steady gas pedal, i can nurse it along. If I pull over and turn the truck off and tunrn it back on, I am good for another 10 miles or depends on the stop and go traffic or hills. I check all the connections. The code says low voltage to bank 1 sensor 1. What could be causing this? Any tips or help would be great. Thanks
