What's wrong with Mercedes-Benz e350 engine?

Hello, I suggest you check whether there is a cylinder shortage first. If the cylinder is missing, the spark plug or ignition coil may be broken or broken. Then check whether the throttle and cylinder have too much carbon and need to be cleaned. Finally, check whether the oil pressure in the oil circuit is too low or blocked and needs to be cleaned or replaced. I hope I can help you. Have a nice trip. If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
