Question about BMW 328
Thanks for using FixYa. A bad 02 sensor would put the fuel injection system into "limp home" mechanical mode. It may run very rich and may result over fueling of some wet plugs. Also check the spark plugs. If still the problem persists, then you need to change the 02 sensor. Engine Shake can also be due to a broken fan blade, also check the fan clutch. It could also be a symptom of a vacuum leak or possibly bad compression in one or more of the cylinders. Please check the idle speed air valve (slide valve) and replace the part whichever is gone bad.
Please do accept the solution if the issue is resolved or else revert for further assistance.

Sounds like its missing on 1 or more cylinders. A check of the plugs and wires is in order, Could be a fouled plug or a loose/bad sparkplug wire. Best of luck.

i just fixed a similar problem on my van there is a rubber elbow on the end of the pvc hose that connects to the valve cover you can only buy the elbow with the hose and it costs about 100 bucks but i guess they have had to replace a lot of these because the new one looks twice has strong you just have to check and see if its collapsed in on itself preventing air movement or leaking the shop will charge you 175 dollars to fix it plus the part but it only takes 20 minutes good luck
