my engine idles at 1,000 rpm all the time. i tried adjusting the tps sensor and the idle set screw with no change i would like to know what you guys think.
Sounds like:
- Car is stuck in ALDL mode (forces idle to be 1000). Check with a scan tool.
- IAC is totally whacked. Reset according to procedures on the web site
- TPS is whacked. Reset according to procedures on the web site (good to do in conjunction with IAC)
- Large vacuum leak upstream of the Throttle Body (bleeding air around the IAC). Check all vacuum lines/connections. A good way is to spray carb cleaner (CAREFULLY!) around all of them and see if idle changes....
My GN Idles @ 1100 in nuetral,..and 900 in gear
I thought this was normal?????
What should it be at?
84 GN idles at 800-850 according to scan tool. set screw in back set with @2-3 threads showing. check above "causes". good luck
