What causes engine to shake?
A worn out or faulty spark plug is a leading cause why your car engine vibrates or shakes uncontrollably. This can result in the engine to vibrate as the cylinders can misfire during idling or at running speeds. Installing new spark plugs is the best way to resolve such vibration related issues.

How long can I drive with engine misfire?
Most cars can run up to 50,000 miles with a misfiring cylinder, and for that, your car should be literally designed to use tough cantankerous, easily replaced air-cooled four-cylinder engines.
Is it safe to drive your car when it's misfiring?
Strictly speaking it is not safe to drive your car if the engine is misfiring. If you notice the intermittent loss of power or poor acceleration, you should get to a mechanic as soon as possible.

There are times when the misfire might not even come from your engine. It could come from the transmission instead. If your car starts to jerk around like an engine misfire had occurred, your transmission may not be able to adequately shift up or down.
Can low oil cause shaking?
Shaking While Idle
Old or dirty oil thickens and does not allow the oil to do its job of lubricating the engine parts. This metal friction can create vibrating or shaking if bad enough during the ride.
How is engine vibration diagnosed?
To determine if a vehicle has an engine speed related vibration, try to maintain vehicle speed at the point of which the vibration occurs then shift into neutral and allow engine RPM to drop.
Can a bad fuel pump cause engine vibration?
A faulty fuel pump that is failing mechanically or is partially blocked, will also starve the engine of fuel causing it to shake or possibly cut out under acceleration.

Why is my car shaking at high speeds?

Can a tune up fix a misfire?
Will a tune up fix a misfire? If it's been a long time since you had a tune-up done last time, it's a good way to start; at least you will eliminate spark plugs and other tune-up items as a possible cause for misfiring. A tune up needs to be done at least every 60,000 miles anyway.
What happens if you don't fix a misfire?
A misfiring cylinder can cause a proportional loss of power. For example, if one cylinder misfires in a four cylinder engine, the car will lose 25 percent of its power. One of the biggest signs your cylinder is misfiring is the loss of power along with odd vibrations.
Can a clogged oil filter cause a misfire?
A clogged fuel filter causes low fuel pressure that results in a lean fuel condition and engine misfire. This can result in poor fuel mileage, rough idling and possibly cause the check engine light to come on.
What happens if I drive with bad piston rings?
4) Poor Vehicle Performance
