Ok i have a 91 civic sedan with a 94 gsr. Car is mpfi and obd1 converted. It has been this way for over a year and with two different motors now. Recently it has been running like sh*t. It starts up and runs fine when it has sat like overnight or for a period of time. As it starts to warm up the idle goes up and runs super rich. The iacv and the fitv are bypassed since they are both bad and made it run worse when they were hooked up. Over the weekend i bought a new dist. and new plugs but it does the same thing. Today it started reving up and down on its own at stoplights and stopsigns. Which makes it a pain to take off easily. If anyone has any sugestions please let me know
