I've been chasing the problem for a month or so now and I'm running out of ideas. Its a 98 chevy tahoe 4x4 with a 350. It's running but it runs rough and starts to backfire after 30 or so seconds. I've got the code po341 camshaft position sensor. I've replaced it twice just to make sure but still throwing same code.I've changed plugs,wires, cap, rotor, crankshaft sensor, maf sensor and camshaft sensor. Checked to make sure I'm getting power at sensor and it was good. The only thing I can find out of the ordinary is on the computers white plug there are two pins on the bottom right side with black wires that look like they got hot. The wires look alright though. I'm running out of ideas and things to change out. Thanks for any info.
