Does anyone have an upstream O2 sensor (new or used but working) that they don't need? I've ordered 2 from ebay for less than the price of 1 around here but I need to wait for them to arrive. I experienced a major drive-ability issue during the week that I thought was the transmission. I checked the computer for codes last night and found a stored p1131 indicating a bank 1 sensor 1 problem. This would explain the bucking and hesitating I had.
