98 xj 4.0 aw4 231
About a week ago while running some seasonal roads i had my CEL light kick on. I had it checked 3 days ago at a local autozone and go the code PO132. The paper says " Oxygen sensor high voltage ( heated oxygen sensor bank; sensor 1.)"
As I understand that, my upstream o2 sensor is no good, and I know this sensor controls the Air/Fuel ratio. However, i'm still getting the same gas mileage ( 138 miles at the 1/2 tank mark) and the jeep still feels like it has plenty of power, but when under load it back fires, bucks, and I experience an extreme power loss. It gets worse if I give it more skinny pedal but if I back off and let it just coast it will come to and be alright again. I got it home under it's own power tonight, but the jeep wasn't happy about it.
Sound like just the o2 sensor or maybe more ? It's only throwing the 1 code.
