Well today i figured out why my car has such a high idle, the throttle body sticks. So if I manually apply pressure to close it with my hand, it idles fine (well I need to tune the idle screws and mixture but still). So that portrays the question.
What would cause the throttle body to stick? I check the TB plate, and unscrewed it and tryed to fit it better, then tightened it down, didnt help. I set the MPS or whatever that thing is called on the TB.. Now im stuck. I can drive the car, but I still want to figure out this problem. Any idea's? Andrew |

QUOTE Well today i figured out why my car has such a high idle, the throttle body sticks. So if I manually apply pressure to close it with my hand, it idles fine You do mean the throttle valve? D-Jet or L-Jet? QUOTE I set the MPS or whatever that thing is called on the TB.. You mean the Throttle Position Sensor (TPS)? There used to be a guy that rebuilt throttle valves on 914's. I believe you sent him your valve and he would put new bushings in it for the shaft and make it work like new. I think his name was Mike Cooley and the company was Southern Knight Machining. I never sent a valve to him so I don't know the quality of his work, but it may be worth a look. I think he charged something like $43.00 to do it. |

Mike Cooley still hangs out on the Rennlist. He joined the 914 Club recently, but I don't see him post much. I don't think he does these TB overhauls anymore. I know that people that received his work were very pleased with the quality. |
