My '01 GT vert has been running rough for a few days for I scanned for codes and got P1132 (Lack of Upstream Heated Oxygen Sensor...Bank No. 1) Crawled under the car to switch the sensor out and discover that I can't get to it. There's no way for me to actually get my hand in there. So what should I do? I need this changed out before Wednesday when I will be needing to drive the car quite a bit. Suggestions?
