Wierd Vibration problem.

So, story starts at the time when I picked a rebuilt 05 ( I know, I know... please don't judge me ) The car drove fabulously for the first 1000 miles or so. But today after a short stop at gas station, it developed a very heavy vibration between 60 and 90 mph. it was worse while lifting off the gas pedal, and not so bad while accelerating. So I drove for about 20 mi, before deciding to pull over and inspect wth was going on. I thought maybe I had warped the rotor while braking hard in the rain. Got out of the car, turned wheels to one side then to the other side, so I could see and check visibly some of the suspension. Nothing jumped at my eyes, so I decided to carry on. Got back on to the highway, and the car drove smoothly like before... One thing I did while pulling over I used brakes heavily again. Could it be something that may need to be looked at? thanks

if it felt engine related id look at the damper, they tend to come loose

speed related or rpm related? see if you feel it sitting still as you take engine up in RPM's.

Here are a couple things to look for that I have come across in other cars with similar issues. Once I had some water freeze in the inside of a wheel and caused a very horrible vibration (it wasn't even that much water)..Another time I had a rock bounce up in a brake caliper and make some very odd noises.

Look for any missing weights inside the wheel

clean the inside of the wheel/brake components well. Look for anything that washes out, it should be just dust.

If it happens again, try changing gears without changing speed, it will narrow things down a little.

It definitely was a speed related issue, at any gear, or rpm. Ill bee keeping an eye on it I guess for now. the car drove okay the next day. thank you all
