Greetings,

My car began bucking after driving for 20 minutes or so. I attached a code reader and it turned out to be the Oxygen Sensor DTC PO130. Unit 1 bank 1 which is the sensor just before the catalytric converter. I replaced the sensor and erased the code but the problem continues. I ran the code reader again and it reported no DTC codes, system pass. Anyone have any ideas? The repair shop wanted 450.00 to replace the sensor. Can you imagine? Thanks Greg

 

i just rebuilt my 2000 s40, and my car was popping. like it wanted to cut off, I had one bad injector ( think that was making it pop) to replace and the cam sensor was going bad.
