Hi Guys, new to the forum and it was recommended by a friend. I have a 1998 tahoe with 160k miles on it. After several different codes prompting repairs I have yet another one. P0507 Idle Air Control RPM Higher Than Expected. I have recently replaced all wiring, tune up, oil pump, battery and cables, radiator flush and refill. I also replaced all O2 sensors, shocks, brakes/power break cylinder. We also cleaned the air intake with a high quality cleaner without removing it and did a run of seafoam through the gas tank. That cleaning seems to have taken care of the misfire on cylinder 4 but I still have the other code popping up. :help: I have found one vacuum tube that was disconnected and since it was dry rotted I replaced it with new tubing. Any ideas on what to do next?
