    Help E30 bogs and stalls

    So last night i decided to seafoam the car, (1/3rd of bottle in the gas,1/3 in crankcase and 1/3 through the intake). Went drifting last night and it ran perfect. Now this morning, I drove the car for about 2 hours and it was fine. Came back home wash the car adjusted the intake and turned the maf 90 degrees. Now I start the car and it bogs, RPM's jump up and down from 500-1200 and dies. So I took it for a drive and in high RPM its fine but when I let go of the gas and let the RPM's drop it dies right when it hits 1k. And when it dies the check engine light is on. So could it be that the MAF is bad or maybe the seafoam just got thru the injectors and causing it not detonate?


    Cliff note:
    Seafoam car
    Drove fine all night and morning
    Then adjusted maf/intake
    Car stalls and jump.

    check your idle control valve. mine got stuck open and it ran simular to your car

    When people ask you what car you drive and you say a BMW and they get all excited until they see it...

      Im going to go check it but would the ICV cause the car to stall out?

            Operator error...LOL

            You did that when you Seafoamed it.... (dincha??)

            At least you found it. is it running right now?

            Cant LOL at you too hard though... I left my dipstick out when I pulled my airbox and drove the car thinking I was stupid for cleaning my ICV and MAF. Even threw a CEL, until I noticed the dipstick still on my workbench.

              No I didnt run any in through the intake yet, but the vac line had a crack at the ending causing the other ending to come lose.
