    aww good point. The vacuum leak was with the PCV valve.

    Vacuum leaks can cause O2 codes due to mixture issues. If you have a vacuum leak, that is very likely your issue. It should be fixed regardless.

    I agree. But I also had an issue with the CEL coming on complaining of the O2 sensor. O2 sensor has been replaced multiple times. Wiring has been checked.

    The car also had a weird issue where when you start to rev the motor that at about 2500 rpms and up it sounds like a 2-step.

    Do I need to use a tune with a m52b28 swap? DME red label 413, ebay headers, exhaust with no cat, K&N intake.

    Have a mechanic that thinks my idle issue is due to there not being a tune for the car.

    He says there is a vacuum leak but thinks that's not causing my issue.

    318is and 24v use the same sized ECU connector. From what I know, the only ones that require opening the firewall hole is the early models (86 and earlier). The Motronic 1.0 and Jetronic used the smaller ECU connectors.

    If someone is interested of doing the wiring harness modification by themselves, I made a video about that: https://www.youtube.com/watch?v=euxmWXAJg9U



    It may miss some obd2 stuff like CEL wiring because we don't have those in use here.

    I wouldn't mind replacing the getrag because second gea wont engage unless revved high or i force it in gear.

    I need to check the shifter linkage, I might have gotten it welded too short and its not reaching the gear possibly?

    pm me with price please
