Asked by Mar 12, 2012 at 07:00 PM about the 1985 Chevrolet C/K 20

Question type: Maintenance & Repair

I've got a 1985 Chevy K20 Silverado with a 305ci V8 engine with TPI from a 1986 Chevy Camaro. For a while now the truck has
had a high idle when in park or neutral (1500 RPM) and when i shift into drive or reverse it drops to where it would normally be,
occasionally the idle will be lower then normal (700 RPM). Also on a rare occasion when i'm driving the truck and stop at a red light
the idle will drop to around 500 RPM or even stall out. Not sure what the problem is but i have a feeling its the IAC Valve, put a
new IAC Sensor in a while back and that didnt help much. Any other ideas?
