it was bank one sensor one thats what the code picks up p0131

no the plugs are not gm but those have been checked out to the right gap and all.

i just wanted to be sure you replaced the upper 02 on the drivers side , and the plugs some work and some foul out gm plugs are the best imo i have never had a problem with them like i do with aftermarket

and you didnt say if the light was on again

thanks

at the time the service engine light was on and the o2 sensor is not on the drivers side it is just after the t on the pipe after the manafolds on the passenger side. now i dont know cuz i went all over the place today and its running fine and the light is out.
