If you got something electrical wet, then yes this is what is causing your problem. You can use an air compressor and dry out all your connectors, sparkplug wire ends, ect. and that should fix it.


Is your service engine light on? I had that problem with my 2003 325ci and it turned out to be a coil pack

If the bucking is not a power loss but more of a jolt, it may be related to your driveshaft flex disks - they may be worn and allow the driveshaft too much play at either the transmission end or the rear axle - or both.....

Same thing happened to me. Check your fuel pump! It seems to be a problem in this model.
