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: 1  Shudder or jerking occurs during acceleration. 2  Staccato shaking, as if over a highway rumble strip, within a specific speed range. 3  Car starts and drives fine for a while, but later begins to shake.

Worn shocks can also allow tires to wear improperly so that they will shake also.es, if your car has shock absorbers it would only be if they are broken in two pieces; if your car has struts then it is probably the upper mounts that are bad. If it is stru â¦ ts and you have the upper mounts replaced, you will also need an alignment. Answered. In Cars & Vehicles.
