I had this "Rough Idling" problem over a year and gone through so many mechanics trying to fix it. The problem started with my "Dinan" chips burned out, then igition core and chip burned out too and then the catylic converter. All these problems made the idling worse. Now all parts are replaced: distr. cap/components sparke plugs wire Mugen chip/motherboard Major tune-up Stock engine - 1992 Honda Civic Si (1.6 liter) I don't know why it's still rough idling at 700 rpm? It's the IAC/TPS/FIT or what? HELP? Any shop you can recommend in San Jose, CA.
