I drive a 1995 honda accord ex with the f22b1. I recently re-installed the stock intake, I just haven't put the resonator that sits behind the bumper yet. While my car is idling either in neutral or park, it revs up and down constantly. My gas has been going down a lot, but I am not sure if that is why. Any input is greatly appreciated. Thanks!

 

Well, I'm not sure if this helps a lot but, I have a 2002 and within the first 2 years of owning it I had a rev problem. It would rev from 1k to 3k over and over again in Park, Neutral, and Drive. I got it to the mechanic and he simply, reset the computer, cleared codes and the problem never resurfaced.

Your problem could just be that it has triggered a sensor malfunction or issue if there is no incompatibility problem with the equipment you installed.
