Code for "bank one, sensor two" kept popping up on my truck. Which is the O2 sensor after the catalytic convertor. I replaced it once before, and the code came back up after a few days. That was last year. Forgot, and ended up replacing the same one a couple of weeks ago. So took the old one and replaced the one in front of the convertor. Pulled it, and wires were burnt, insulation melted, and one wire was broken. So far so good. Ordered a new "cat back" exhaust from LMC truck. going to pull the bed off, to do that, and go ahead and replace the fuel pump while its off. Not going thru the same thing I did with the Blazer.
