There's so much **** wrong with my Tahoe I don't know what could be the cause of whats even going on anymore. If I put my foot in it at all it chatters and and has no power until it gets going a little faster then totally clears out and is fine. I get on the highway and it just annoys the living piss out of me. Constantly is missing and chugging. On Cruise and all. Don't do it when not on the gas. Has a high idle also. Code says Crank Cam shaft relation. I've replaced both those in last few years. I dont think its fuel related. Could I unplug cam sensor and see if anything changes? Or is that too hard to get at or a bad idea? I dont know if the high idle and "running by itself" when driving so to speak is a relation to the chugging and missing on highway, and in town if I give it gas? I just..Got zero dollars either. Gas is just killing my beyond belief.
