possibly a broken or missing engine mount
the engine mounts could be bad
Engine mounts
The pistons are running in the cylinders of the engine, so when the rpm of the engine rises, the pistons quickley build up speed. It is this rapid acceleration of the pistons that casue the car to shake.
Failure of the engine or out of petrol
Engine miss or rough idle, or broken motor mount
a bad engine
major vacuum leak?
The car might need a tuneup . also the problem might be related to fuel injectors that are not working properly.
No, not unless it is so low the engine is overheating.
no.an engine can run on 3
Due to the fact balancing the engine would be impossible. It would shake itself to pieces if it ever ran. It would be very heavy, shake the car apart and have no torque
because it is going on a rollercoaster of car sensations.mmmmmmmmmmmm.
