M42 Dead Cylinder?

Was wondering if anyone has any leads to diagnose my problem...
Iv'e got this 91' 318is with about 130k on it and the engine stumbles at idle, but generally smoothes out at high RPMs. Im not quite sure if I have a dead cylinder or what? All of the coils produce spark and I changed the spark plugs. Could faulty fuel injectors cause this same problem?

Thanks!

Bad fuel pump, bad idle control valve, bad airflow sensor, vacuum leaks among other things could cause this kind of problem.

do a compresion test, put up your numbers. that will tell you if you have a serrious problem. if you have good numbers, then check all your vacume lines for leaks, usualy the boot from the maf to the throttle body develops cracks, even small ones that you can barley see cause these symptoms. also could be any other vacume line. check your air filter, fuel filter, and clean your maf and idle control valve. if any of these arn't the problem then let us know.
