so i went and got my codes read today and i got 5 freakin codes!!! #3 cylinder misfire #4 cylinder misfire, circuit malfunction, knock sensor circuit malfunction and random misfire this is a crock of shit lol the common "probably cause" for the misfires is a vacuum leak, i think this is why my cars doin the same shit, after i install my new header tomorrow ima try to get it runnin, the circuit malfunction is my faulty speed sensor it doesnt work, the knock sensor i think is because its not plugged in not that much of a problem cause if the car knocks ima obviously hear it lol anyone got a write up of where my vacuum lines r?
