Basic:91 Crx w/b17 swap, still obd0 with my pr3 ecu from my old b16 swap. Everything was fine til my stage 1 cams went in last night. Car seems to be running fine but my check engine light is going on & off, with long flashes, the light on the ECU is NOT on or flashing. If Im driving under normal conditions, not getting on it in the least bit, it doesnt come on, but if I accelerate a bit like getting on the interstate this morning or downshifting to pass a car, it starts flashing. It reset this morning while I was stopped in traffic, but then started flashing again once I got going.
