Hello all. Trying to narrow this issue down. Cruising at highway speeds between 1700 and 2000 rpm the car shakes pretty bad. Anything below 1700 or above 2000 is smooth. I was thinking U-joints or drivshaft but if the car is idling and you rev it up when the rpm's are dropping down the engine shakes between the 1700-2000 rpm range. No check engine light but the issue slowly getting worse. Idle Air Control Valve maybe?

Do you live an area that gets snow? If that's the case make sure you don't have a lot of snow/ice build up in your wheels. Because that build up will cause the same thing to happen.

if the engine shakes when the car isnt moving at the same rpm range and when it is moving, the problem is most likely a missfire or accessory drive inbalance
