i cannot find the idle adjustment screw on my car. according to the fsm it is in between the 1 and 2 intake runners. i looked everywhere around the intake manifold and i couldnt find any kind of an adjustment screw anywhere. can someone please tell me where it is at and what it looks like. also, do i adjust it while its running or when its shut off?

its at the back towards firewall, below intake runners somewhat, youll see it. pretty easy to find. unplug the tps sensor, then adjust the screw/idle. HTH

I’m not sure where it is, but i'm pretty sure the tps (throttle positioning sensor) has to be unpluged so the computer doesn’t try to correct for what you just changed with the screw.
