Engine Problems

There are times when a strange vibration might be a sign of engine trouble.

Sometimes a shake or shudder will emanate from the engine compartment, because the engine isn't getting enough air, fuel or spark that it needs to run smoothly.

Symptoms that might indicate such an engine-related case of the shakes include the following:

  • Shudder or jerking occurs during acceleration
  • Staccato shaking, as if over a highway "rumble strip," within a specific speed range
  • Car starts and drives fine for a while, but later begins to shake

These symptoms could be signaling that it's time for a new set of spark plugs. If the plugs are fine, it could be that the spark plug wires need to be checked (are they connected in the proper order?) or replacing.

Lastly, a dirty air filter or clogged fuel filter can starve the engine of needed oxygen or fuel, respectively. So be sure to replace them at the manufacturer's recommended intervals.
