I step on the gas from a stop with the car at idle.I step on the gas and the car has no power.when I let up on the accelerator pedal,it starts to pick up speed but is very sluggish.Eventually the car runs normal with correct power.the misfire seems to be getting worse,so what could be causing this problem?

There could be a couple of reasons. Yes a tune up would be nice. But my not fix the problem. If you are not losing acceleration on straight away but on hill, then it could be the torqe converter. Also have your MASS airflow sensor checked and air filter.
Also check your fuel pressure at the fuel rail. Get a fuel gauge and look for a port on the fuel rail for a port that looks like the valve on the tire. Screw it in and crank the car. You will have to call the part store to find out what pressure it is supposed to be. If there is low or eratic pressure the its the filter or pump

Sounds like a fuel filter issue. If the filter is clogged or is getting to the point where it's going to be clogged badly the amount of fuel going to the engine will be restricted. This would cause your stated problem. Theoretically there isn't much of a need to go over 4000 rpm unless you are racing with the car but I think most bimmer owners can understand where you are coming from:) As far as the 1993, I'd check all your intake piping and vacuum lines and make sure there are no leaks whatsoever. An easy way to check is to have the car running and spray carb cleaner on the intake piping and such and see if your revs increase, if they do you've got a leak. Hope this helps! I'd be glad to help with any other questions you might have a please don't forget to rate me.

I'll keep this very short. Replace your Mass Air Flow sensor(MAF). You can get a used one usually and be just fine. Check out silverstar auto recycling in Fresno, CA.. Great service. I've done a lot of business with them.

Disconnect the battery completely, try turning the key with the battery disconnected. Put the battery back together. The check engine light should be off now..
