I swapped in a 94 B18b1 into a 91 crx dx wired to obd-1. The car runs pretty good its basically finished, theres only 1 problem that keeps on bugging me. A couple of times that i've let me car idling so it can warm up i have left it on for a while it will idle like at 900 then all of a sudden the idle will go down to like 600-700 and then the "check engine" light will come on all of a sudden. then i just turn it off and turn it back on and it goes away. this has happend only a couple of times, not all the time it just bugs me. does anyone know what this could be any help is appreciated. thanks
