Ok my car is idled at 1100-1300 in park/neutral. i tried to turn the idle down by screwing the gold screw on the throttle body but it didnt do anything. so the Shop Manual says if necessary, adjust the bolt on the A/C Idle Boost Solenoid Valve. i dont know where that is and it only shows a pic of the valve itself and no location or picture, does anyone know where at on the FI Engine this bastard is located??? plz help, thanks

It is on the front of the driver's side of the intake plenum.

The plenum is the part of the intake manifold that all of the runners connect to. It's volume affects wheter the engine breathes better at higher (like racecar) or lower speeds (like a truck).

You can find it on your car if you look to the right of where it says PGMFI, its just below that point. This diagram shows the intake manifold reversed from where you will be standing in front of the car. I believe its #12. Someone please correct me if I am wrong
Honda part# 17235-PH3-901
VALVE ASSY., IDLE UP $93.20

If you make a junkyard for one it needs to be off either an 86 or 87 model, or an 85-87 Prelude with your exact engine.
