i have a 96 gsr in a 94 hatch. my problem is that my car when warmed up revs constantly from 1100 to 1450 non stop, what a head ache. i was told it might be a vaccum leak, i was wondering if anybody know which vaccum lines to check, if you have a pix it would be nice. the other problem could be: i custom my throttle cable and it is hella long, but the gas pedal is fine; it engages normally. could it be the iacv, how do i find out which is the problem?

 

come on, anybody?

 

Get a can of carb and choke cleaner and spray around the intake [specifically where the manifold bolts to the head], throttle body, and any vacuum lines that go into the intake manifold. If the idle speed drops a bunch when you spray a certain area, that's where your leak is.

 

Thanks ill try that out.

 

I have a factory service manual for a 96 integra here is what it says. Unplug the Idle Air Control Valve (IAC) 2pin connector if the idle drops or the engine stalls adjust the base idle speed if not replace the IAC valve. There are several other things to check TPS sensor correct output ECT correct output Throttle body clear and not clogged intake air hose loose and leaking if you have an automatic the fast idle thermo valve malfunction. Correct ignition timing vacuum leak. All of these things effect your idle. To adjust the base idle speed run you car up to operating temperature and then turn off your car. Disconnect your IAC valve and then start your car again and rev it up a little bit and then slowly let off until it stabilizes. Then adjust your idle speed screw if necessary by turning your idle adjusting screw with the IAC unplugged you should have a 480 +or- 50RPM. Then turn off the ignition and reconnect your IAC valve and remove the backup fuse in the under hood fuse relay box to clear the code it should be a 7.5 amp fuse and then start the car the idle should be 750 + or - 50RPM. Hope this helps.
