328i. Specifically, it's a 2007 [pre-LCI] 328i 6MT Sedan w/ Sport Package w/ ~210k miles. I'm experiencing an odd shaking and vibration throughout the car whenever I accelerate. It seems to get progressively worse as I climb through the gears until it's almost unbearable at any speed requiring gears 4-6. The shaking is worst under accelerationThe vibration is worse when in gear than in neutral. In gear there is a much greater load on the engine. Power is being transfered to the transmission and then to the wheels. This is going to cause the idle to drop a bit and this is where you'd feel the most vibration. Also the problem is worse with a warm engine/transmission than when it is cold With a condition such as this, it is normal for it to run rougher when electrical components are tuned on and it is normal for a car to run rough when the idle is to low. My first instinct here is to clean the throttle body, fully warm the car, connect a scanner, and command the IAC (Idle Air Control) valve to move the idle high and low to see Why is MY BMW shaking at idle? A BMW shaking at idle could have several causes. Bad motor mounts is one of the most common culprits in older higher mileage vehicles. Other common causes of a shaking idle include bad fuel injectors, spark plugs and a vacuum leak. Performing a basic diagnosis of your BMW shaking at idle problem is relatively easy.

The idle did not throw any codes, my idle was not sporadic, the car would just vibrate and shake while stopped. It happened in both gear and in neutral or park. My car has 93,000 and I replaced the plugs, coils, oil separator, cleaned ICV several times, removed, replaced fuel filter, performed the famous sea foam through the intake, and checkedWhat causes BMW rough idle? If too much air is added to the air and fuel mixture, then your engine will be rough idling. A dirty fuel injector can also cause rough idling. The fuel injector administers the correct amount of fuel into the engine’s cylinder at the appropriate time for a smooth function. Why is my BMW 328i engine shaking?
