I just bought a 1990 h22 accord and I just cant seem to find out whats wrong with it. Its throwing a straight CEL, but it blinks one time even if I dont jump the cel. It wont hold a idle, wont rev up past 4kish rpm and bogs under WOT. Ive been told it could be the o2 sensor, so I replaced it. I also found that the oil pressure sending unit was broken so I replaced it, and ive been told that the ecu might be bad. There is also a wierd buzzing noise coming from the injectors aswell, I have a video to show whats going on.
