Throttle wire - loose 200

posted by  someone claiming to be hillbilly on  Thu Jun 27 02:21 CST 2002 [RELATED]

I think that you are confusing the pressurized gas line (which you say was replaced) with the throttle cable. The cable connects at the throttle body and operates a butterfly valve to control air flow to the engine (engine speed). It shouldn't affect idle speed which is controlled by the engine computer via the idle control valve when the butterfly valve is closed (slack cable). If there is excessive play in the cable it would likely show up in the accelerator pedal as loss of engine revs (top end). Since it was idling correctly before the hose was replaced I would look for loose wiring connections and also check that the micro switch on the throttle body is closing during idle. You should be able to hear the switch click just as you open the throttle slightly. No click, rough idle. Also you may try resetting the engine computer. Remove the negative battery terminal for about 2 minutes and re-connect.
