I have a 2000 Accord 2dr. My suspension is still stock. I was doing 80 mph on the freeway until my car started shaking. Does any body know what can I do to fix this problem. What should I be looking into. My allignment is already been fixed. Thanks.

If the alignment is ok I would suggest checking for play in the tires and also check if there is a little kid stuck to your bumper causing drag lol

Does the car shake at all speeds? Check tire pressure first, then if problem persists, rotate your tires front to back. then if problem still persists, tire imbalance, or worst case scenario, bad tie-rod.

Jack up your car a tad but not to the point where the tire is off the ground, push on the wheel for wheel-play.
