Nope idle is set right at 850-900. I have been all through this and havenít found any reasons for it. Everything in the intake and boots are sealed very well so I donít think itís a vacuum issue plus I canít find any vacuum leaks. If it were a sensor the fi light would throw a code and the the ohm testing of the wires would of showen any issues there. I even changed the throttle body thinking it was the tps. I would of thought if the valves had different clearances it was causing a slight timing issue in the valves at low rpm. Iíll keep digging tho
