CAR SHAKING

Pontiac Sunfire

4 Cylinder / 2 dr / 2005 Pontiac, Sunfire (35000 miles). My car runs very smooth until I pick up speed on the highway at about 65mph. Has good take off speed and I've had regular oil changes. However, the car is two years old and has never had a tune up. Could that be the problem? I've never had this problem before. What could be wrong?

It certainly would be smart to replace the fuel filter, but this is not related to the problem.

Very good chance that you have a wheel balance problem. This may be from an out of balance wheel; a bent rim; or ice, tar, or mud build up on the inside of the rim.
