    Check engine light & Fault codes

    Platform: 1990 325i M50 swapped (m50b25TU)


    Problem: I have a heck engine light the comes on and off sometimes. First it was cause the purge vavle off the charcoal cannister wasn't Hooked up too anything...just dangling. So I googled n researched where to put it and aPparently it goes under the intake/throttle body on the little nipple/fitting.
    But another thing I noticed is when I start the car I can smell gas (FPR is capped off for running a higher pressure) and so is the little nipple by the intake temp sensor under the manifold.

    Did a stomp test and I get code 1222 Lambda control#2?
    Because V8

    ecu does not know that fuel pressure regulator is not getting any vacum and when it tries to fix the mixture it fails to do so. You got to connect all components as if it was in e36

        1222 90% of the time is a vacuum leak.
