So its an 89 Acord DX. Carb not FI. Manual trans with AC.

Idle is high at 2500 RPM. I've found that after warm up its stays high. I can hook up my vacuum checker to the (for lack of better term) choke pull off and after putting vacuum on it the idle will come down. The line is hooked up but does not seem to have any vacuum coming from the engine. I''ve sprayed some carb cleaner on the vacuum lines and don't get a real perceptible change in idle so I'm thinking no vacuum leaks. The hoses are in good shape and I cannot find a broken one. I've tied the pull off out and the idle will settle down to under 1000.
I'm assuming the "choke pull off" is the doo dad that hose 18 and 26 plug in to. ON a chevy it would be called the pull off. can't find it in the chilton to know for sure what its called on a honda. so any idea's on where to go to get some vacuum?
also does anyone have a pdf of the vacuum hose diag? Its a b tch trying to look at the underside of the hood. thanks
