    I use a lot of fuel cleaner. doesn't work.
    (I have new plug, fuel filter, o2 sensor.)

    I had that problem, it was a bad coil for me that caused the misfires and it felt like it wasn't running on all cylidners.
    That's what she said.

    more then likely a coil pack or a major vacuum leak.. check your TB boot and hoses..

    94 325 always in pieces
    a pop sound would be misfiring, at least on my 325 it was. After buying new plugs, and seafoaming the car it was fine. hmm..
