1994 Honda Civic Idle problem?
T hey have a 1994 Honda Civic swap with a 1999 JDM motor. i cannot figure out my problem. when I move Nutral the car has a idle jumping up and down from 1000 to about 1700 RPM, its boring and sounds like rev im "ING engine. heres the catch, I already takin the IACV and it wasn't even plugged Buti even sprayed carb clean on him, let it dry and reinstall it. I also already bought a new PCV valve today also, and put gas in the dry gas to clean fuel lines, nothing seemed work and I need help! thank you
Vacuum leak or defective IACV. If the IACV is bad, no matter how this thing you clean the car is gonna idle like crap. Pass on the wiring and everything on the intake manifold and make sure nothing is loose, broken, and everything related / Wired correctly.
