My friend and I recently r&r'd the headgasket on his '94 pick-up. Runs well but the idle is high, staying ~1000-1200 when warm.

Timing is spot-on, no missing vac lines that we could find. Manual says ECU sets idle, but we suspect a mechanic may have fiddled with something in the past.

Question: If we mess with the throttle (looks like there's a stopper screw) will that allow a lower idle? The only other thing I can think of is a leaky intake gasket, but it's all new stuff in there. Or maybe we screwed up a big vac line beneath the intake?

Thanks for any insight/suggestions!

yes you can adjust the idle useing that flat screw try that first and let us no

Yep, there is an idle-adjust screw on the throttle body. That should do the trick. If it doesn't, you can try to adjust the throttle cable itself.
