07 avalanche p0302 code driving me nuts...
hey guys, i bought a 07 avalanche, 5.3L 2wd. it has a p0302 code and I cant seem to get it to go away.
what I've done so far... Plugs Wires Coils Injectors Smoke test (found a broken pcv pipe on the drivers rear of engine...repaired) it does have a little miss at idle, my next recourse will be compression test on the cylinders and look at the cats. I pulled live data today with my scanner but don't see anything here is a readout sample, tell me if you see anything in the data. Thanks in advance!
