    1986 325e won't accelerate.

    I just bought my first project car, a 1986 325e. Automatic.
    The car starts up fine with no problem but when I try to accelerate, it doesn't go anywhere maybe like 5mph... Even if my foot is flooring the gas pedal, sometimes it will get going but no faster than 10-15mph. I was told it might be a Mass Air Flow sensor, but I'm not sure I'm still learning this is my first build. Thank you.

          Yeah it revs up and rpms go up aswell, there's a horrible sound coming from my catlytic converter, and also when I start it up you can smell the gas from the car super strong.

            I had this issue.

            Mass air flow sensor fixed it.

            Does it chug if you try to fluctuate the pedal? Grab one from the junkyard for $40, is what I did. The 5 series ETA fits it too.

            Good luck!

              Yeah man it chugs and gallops, so a new MAF should do the trick?

                Just so you know, your car doesn't have a MAF, it has an AFM. That is a likely cause however. Could also be bad fueling (filter, pump, injectors, etc). But try the AFM first.

                      Did this car sit for some time ? Did you open the air box to check for a mouse nest ?
