Q: BMW 318i, car is shaking. Why?

asked by on

Hi when I start my BMW 3 series 318i 2010 (automatic) the car shakes and the revs go up whilst in park mode. I get out of the car and the exhaust pipe is shaking. When I drive the car it stays stuck on the first gear for while until you hear a bang noise and the gear changes some times I have let go of the gas for it to go to the next gear. When I put the heating on or the AC the car sometimes starts to shake and the acceleration goes heavy too.
My car has an automatic transmission.

Hello, thanks for writing in. It sounds like you may have a serious internal engine issue, something may have come disconnected, or you have bad gas. I usually check the computer for codes first. If the computer is seeing a problem then it will be stored in a code and that will give direction to the issue. If there is nothing there then a visual inspection of the engine must be done followed by a compression test. If you need to have this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair this.

Q: Rough idling, no power on acceleration, revs by itself, shuts off

The first thing I check for in any drivability problem is air leaks. Any air that gets into the engine without going through proper channels will lean out the system and cause these kinds of problems. Look under the hood...
