I have a 93 325is.It performs nicely, but, when accelerating away from a stop it will sometimes sputter. It feels like, if this car had a carb,its loaded up and to rich. Of course it doesnt have a carb but thats what it reminds of. If I let up just a little on the gas pedal and then reapply power it will usually clear up. It will happen sometimes if I lug the engine in higher gear, but this has only happened a few times, cuz I usually dont lug the engine. If I dont lift off the gas and just stay in it, the sputtering will continue for anywhere from just a few seconds to upwards of 10+ seconds and then clear itself and accelerate normally. Any help or suggestions would be greatly appreciated.
