Allright guys, I have an O2 question. I have had a SES light on for about 3 months, I had a difffent PCM in the truck from Wait for Me, and I never got the crank relearn done. So I thought the light was just from that. I sent him my factory PCM to be tuned, because that was cheaper than going to the dealer and having them do the crank relarn. Well with the factory PCM in the SES light went away for about 2 days, then it came back on. So I took the truck to Advance Auto to check the code. It came back with codes of P0135, O2 upstream heater performance, and P1133, O2 insufficent switching, both saying left bank. So I decide to buy 2 overpriced O2 sensors and have the codes reset. Well I started to take the passenger side out first and realized that with the Pacesetter Headers, I cant take the O2 out because there is not enough room between the headers and the frame, I guess I will have to loosen the header up to replace the O2 So has anyone else had a similar problem, with their O2's, and header clearance? And just to make sure, the left bank is the drivers side right. If I change just the left bank will it be ok, or should I go throught the hassle of changing both. Input is greatly appreciated.

 

Nobody
