    M30b35 Stalling

    Haven't figured this out yet. I have a video here:

    I've replaced all ignition components, coolant temp sens, battery. Crank sensor checks good.
    The car stalls when coming to a stop and hesitates right when pulling off or reving. Please help.

    Not exactly the same car but my 91 e34 with the same motor did the exact same thing. Was running great and slowly started to cut out on/off, especially coming to a stop and taking off from stop, got worse and worse. it was a horribly clogged catalytic converter. Got worse and worse till I couldn't drive it. Replaced catalytic and it's running perfectly.
    Also, even being an 89 I wouldn't rev the motor like that in P or N, could fry the A clutches even though the trans has the updated relief modifications.

    I hit the cat with a hammer and put in a good ecu, and the problems have gone away. Hopefully it's fixed!
