ok i got a 91 civic jdm z/c 1.6 DOHC. and i checked my ECu light cause i was having backfiring problems and lose of power and i got 9 blinks from it but no check engine light was on. What do i actually have to replace to fix it. I know 9 is the No 1 cylinder sensor or some shit but the part was like 150 bux and im not even sure if it will fix it
