Pretty recently I have been having issues with a high idle (about 1500 rpm) I checked the voltage at the tps, its at about .925 volts. The Iac is not sticking open and it is relatively new. There are no vacuum leaks that I know of. The truck and engine are from 86, the wiring harness and computer are from an 87. The egr system was removed before I got the truck about three years ago but this never gave me a high idle before. The only other code I'm getting right now is one for vss circuit open.
The 86 didn't have a vss from the factory and the open vss code just popped up about a month ago even though there hasn't been a vss hooked up to it since I put the wiring harness in about 2 years ago. Could this cause my high idle? I don't know anything about how this particular circuit is used by the computer so I'm at a loss. Is there anything else that could be causing the high idle that I could test to figure out if, it is bad? Or could this condition be attributed to the fact that the motor has 263k miles on it?
