Bought this car in May 05, put a reman in it in June with all new silicone hoses.
Engine runs great, broke it in properly. Idle speed has been high since I put the engine in. I figured no big deal, it just needed adjustment. I broke out the factory manual last night and tried to adjust it. The Air Adjustment screw was already screwed in all the way so I tried the idle screw with the lock nut on it.
No change. I can adjust it faster, but cant get it below 1100rpm. I read on another thread last night that a vac leak can cause fast idle. This seems an unlikely cause although I haven't tested yet. What else can cause a fast idle?
Any suggestions?

Only mods are downpipe, catback and Apexi intake.

 

Check the throttle-cable adjustment. If the throttle cable does not have enough slack, it can hold the throttle slightly open. Also check the cruise-control cable - same reason.

Other things (faulty PCV valve, for instance) in addition to the usual vacuum hose or gasket problems can cause high idle.

 

Cool. Thanks! I'll bet it's that throttle cable.
Cruise control? We dun need no stinkin cruise control.
