Car shakes


Could be a fuel , spark or compression issue. Does it smooth out if you give it more gas ? Does it do it hot or cold or either one ?

When i step on the gas the car vibrates and shakes


Is the engine running smoothly? Does it only vibrate when loaded? If so, then Yes, check the motor mounts. While you or a tech are underneath get your driveline and suspension mounts checked. A bad suspension mount could give the same symptoms. You don't say how many miles but if its anywhere near 100k then mounts are a definite possibility.

Car shakes when idling'


Well this could be caused by a number of things. But the most common cause is an "engine miss." You could have 1 cylinder that has stopped firing. This will cause a very rough idle and very possibly shake or shudder whenever you accelerate. Another cause may be a main "vacuum hose could be disconnected" from it's port. Vacuum leaks cause engine shake at idle. Check for loose, cracked, or disconnected vacuum hoses under the hood. The third and least likely cause is a "broken or worn motor mount". If the engine is not securely held down in place by all the motor mounts, it will vibrate excessively and cause a shake at idle. The engine miss and motor mount problems are 2 issues best left to a professional to tackle. But as I said, you could tackle the vacuum leak issue yourself by checking under the hood. Hope this helps, good luck!

When i press on gas peddle the truck shakes


Is the check engine light on? Could be that the engine is misfiring, or broken motor mount causing the truck to shake when you press the gas pedal.

M car started to shake and enginelight flashed...i purchased spark plugs and wires like the salesperson said to and said it would stop but it still does it. i have also addedd "heat" to the gas tank...


Possible broken motor mount. A broken motor mount can do that. To check to see if one is broken ,open hood ,start engine,press foot on brake hard,put in gear and give it some throttle.If the engine moves a lot then u have a broken motor mount.

Trans mount?


The moun sounds like it is probably bad. But you are addressing SHAKING. Most motors don't SHAKE. It may have a miss to it or not be running smoothly. It may need a tune up or have bad gas. Just remember this car is 12 years old and may need some simple TLC.

The ONLY thing it could be is tire out of balance....
