Joe thats rather weird. You didnt touch anything else?sirrach said:Hey guys,
I posted this in fuel delivery but no luck. I just finished installing walbro fuel pump and now after a few miles I am getting code p1038 (o2 sensor bank 1 sensor 2). I have stage 1 which makes no sense to me and the sensor is still plugged in. I have been running it like this for a long time, which makes me think that something else is setting it off.
Any ideas? :stab:
