Is your CEL on and your top speed capped? BMW's have a "limp home" mode when you throw a serious error.

Same symptoms, can't figure it out.

is very hard to pinpoint your problem. it could be a combination of things. maf, vaccum leak, vanos, ccv, icv, it can also be your camshaft sensors (exhaust or intake). you should have your scanned by a bmw reader, so it can check all of the modules of the car. search the forums there are quiet a few threads with the same problem..

Get a peake research code reader not the generic one from pep boys it will save you money in the long run

Have u checked ur intake manifold actuator? pull it out and check if the flap is broken... if it is then ur probably gonna have to buy a new one...

these cars have no spark plug wires, they are all coils
