Ghost reving between 1000-1500 RPM 1990 accord ex-r
Hey everyone,
Love the forum, helped me loads with my current 1990 accord. Now my current problem is a ghost rev between 1000-1500 rpm's when the car is idling. And it doesn't do the ghost revving after first starting the car, it only does it after I put it in park after driving for awhile. If I turn off the car and start it shortly after and the ghost rev will disappear.
I have tried changing the FIV secondary valve that is only available on north american cars and it seemed to work for a bit then the ghost rev returned again. Should I replace the main FIV or clean it out? I tried tightening the top (the plastic ring top that is inside the FIV, easily accessible) on the FIV but that didn't seem to help either.
Thanks in advance for any help

Remove your intake tube that is attached to the throttle body. Look into the throttle body and you will see two ports. these two ports go to the IACV and the FITV.
With the car running slowly cover each of these ports one at a time and see if that smooths out the idle at all. If it does then you at least know whether it is the IAC or FIT that is at fault. Now if covering ether of those ports does nothing to the bouncing idle then you have a vacuum leak somewhere else. Ether a cracked/worn vacuum hose or worn gasket.
A bouncing idle can also be caused by a dirty throttle body, faulty engine coolant temp sensor or air bubbles in the coolant.

Same problem with racing from 1000 1500
Im having the same problem with my 1990 Honda Accord ghost idling from 1000 to 1500 RPMs. I tried as suggested taking the intake tube off the throttle body and when I plug the top hole of the two holes inside the throttle body it all but killed the engine. Covering the other hole didn't do very much at all. Any help would be very much appreciated, thank you very much

Welcome to forum.
I've had a '93 and now a '92, both 5 spds; both of them do the rpm oscillation during warm up if I touched the gas pedal, but not otherwise. The oscillation lasts about a minute, is clearly engine temperature related, and goes away as car warms up. So I let the car idle for several minutes without touching gas pedal = no rpm oscillation.
