i have a 91 si hatch obd 0- obd 1 convert w/ a d16z6 swap. im runnin a po6 rght now but just got a p28 from the junkyard. its out of an automatic (i have a stick) ut it ran ust fine when i plugged it in. the only things were it has a check engine light and the rpm's are hopping. is there a way to either convert the ecu to a manual or clear the code and fix the idle?
