Car making loud sound and vibrating after filling up with gas(1997)

After filling the tank up and getting on the highway the car started making a loud sound that made me think that it was switching to the next gear properly. However, the RPM's were around the 2 - 2 1/2 mark so perhaps that isn't the case. The car also vibrates the louder the noise gets. When going from a full stop the noise is especially loud (and the vibration especially strong). The sound seems to be coming from under the hood. Turning the car off and on again didn't fix the problem.

The car has 180k on it. My father mentioned that it could be a possible exhaust problem. Any ideas?

Thanks so much for the help.

Have you had any water or rain? Washing the bay, etc? Could be a misfire due to moisture. Are you sure you didnt put diesel or some other fuel. E85 or something.
