hello, I really need someones help. I have a 2007 silverado 4.3 and its not
running so good, that I mean it kicks from 1st to second... revs high but not
really high. and I can't get rid of the p0174 p0171 codes which is bank 1 and
bank 2 running lean. I've replaced the MAF, Intake manifold, TPS sensor, MAP
sensor, and other little things.
Im sorry its a 4.8 not a 4.3
Is your exhaust system leaking? A leaking exhaust system can pull fresh air into the exhaust system and cause a false lean condition. Hope that helps! Jim
there isnt any ticking coming from anywhere though. I'm gonna try and do a diy smoke test but I had the gaskets professionally done.
