Re: '91 accord low rpms

I have the same issue too. Especially when put in gear or have AC on, the RPM sometimes drops to 250 and the engine chatters pretty bad. Don't have a chance to dig into it. But as far as I know, it's either the IAC valve, idle adjusting screw, or wiring (signal ECM to open IAC when in gear or AC on).
