Ive had the cel light come on and off for a few days now. I finally got a chance to check the codes and it game me code 139. My buddy didnt have the code book. If anyone knows what that is, let a brotha know

THanks

P0139 O2 Sensor Circuit Slow Response (Bank 1 Sensor 2) Aftermarket exhaust? leaded gas usage?

 

Buschur? take the o2 sensor out and see if the drillhole flashing is partially covering the hole

 

Thats what I figured. Thanks mp5! When I installed the exhaust I noticed the small drilled hole which I thought was pretty smart to trick the ecu. THere wasnt any debris in the hole. Does that little hole trick always work? If not what can I do to stop that from triggering the cel light? Do they may 02 sims for our cars? I guess I can call Buschur and ask them whats up. Will that cause the car to run poor or just annoy you?

Thanks

 

Just annoy it also culd just be clogged with suit
