Loss Of Power And Vibrations While Accelerating

[mozartean]

I need urgent advice here. I am driving a 3-year old right-hand drive E46 318i automatic. This morning, when I turned on the ignition, the car started to vibrate at idle speed. The tachometer needle was quivering around 750 rpm. When I stepped on the gas pedal, the acceleration was sluggish as though the handbrakes were still on. (I checked and confirmed that the handbrake was released) Whenever I stepped on the gas pedal, the vibrations would start until I lifted up the gas pedal. Otherwise, none of the warning lights were on. This is the first time that this has happened. What could be the problem? A friend suggested that the fuel injection system could be clogged up. Please advise.

fuel injection system could be,but before,check the coils that are located on the Black(electrical shots)....

It could be , but I would check the battery first, it could be the car not getting the adequate amount of current.
The injection system should not not really get clogged up, the gas filter is supposed to prevent that.
It could be any number of things , so if it persits you should consult your mechanic.

Thank you guys for the information. I sent my car in and was told that there was indeed a problem with the fuel management system. The problem is now rectified and driving is now a breeze.
