I suggest you send me all your money! Would you do it? EGR valve doesn't cause car vibrations. Don't start changing parts based on suggestions... Have it read for codes, even if the check engine light is NOT on the computer will have stored information and codes. Discount auto stores will read codes for no fee. write them down. OF course check all the tires and rims and rotational parts.

I have had the same vibration once (traveling long distance) and often rocking like a boat (after hitting a bump or on freeway) in my 2002 Sonata. As soon as it started vibrating I pull of highway and had tires balanced again and nothing. The boat rocking stopped after replacing broken BUSHINGS the first time. 4 yrs later it happen again and I repaired several items (shocks, struts, lower arm controls, changed brakes and rotors, bushings and bearings) and tires are not to bad, so far the vibration has stopped, but it still rocks sometimes. I'm not sure which of those repaired items actually fixed the vibration, but I still need to find why its rocking. This car has been so faithful!
