Help with fast idle on LS1
I have a 69 Camaro now with a newly installed 2002 LS1 and T56. My current challenge is a fast idle that will pull you along at 10 to 15 mph while in 1st gear without touching the gas pedal and the RPM's will increase when you put the clutch in until it eventually drops down on it's own to a normal idle. What's most likely at fault here (maybe the TPS, Throttle Position Sensor?) and is there an adjustment I can make or is this something best left for a professional tuner?
