one eye Posted June 1, 2008 Share Posted June 1, 2008 My roommate has an 87 GL10 turbo wagon And I was going to turn the idle down but I for the life of me cannot find where to do it at. Does anyone know where it is located, cause I sure don't:) Jeff Link to comment Share on other sites More sharing options...
Gloyale Posted June 1, 2008 Share Posted June 1, 2008 My roommate has an 87 GL10 turbo wagon And I was going to turn the idle down but I for the life of me cannot find where to do it at. Does anyone know where it is located, cause I sure don't:) Jeff Stand at the front of the car and look straight, directly down at the Throttle body. Behind the throttle bore, at the rear left corner is a screw head in a recessed hole. A bit smaller than a dime in diameter. Right next to the Fast Idle Solenoid. IIRC screwing it in lowers the idle. ****Do NOT mess with the painted stopper screw on the throttle shaft.**** It is set at the factory. If adjusted the throttle plate will either close too far or not far enough. The ECU needs that closed throttle position to be a excactly right to regulate the idle. *note, If you're problem is a fast high idle(warming up idle), the fast idle adjustment screw is on the rear of the throttle body base just under the fast idle solenoid. It is adjusted from the *horizontal*, so you have to look for it from the rear, and probably use a stubby screwdriver. Link to comment Share on other sites More sharing options...
