Thanks everyone that answered. This morning as I drove, the vibration got worse and since I need the car for work I couldnt wait to try fixing it myself on the weekend. I figured I'd get stuck somewhere. So I brought it to a mechanic. It was the U joints, which ones - I forgot to ask. Good guess Toolmakerprevo! As for the gas problem, they didnt see anything obvious but recommended a tune up. that I'll wait till the weekend to do. Even though its supposed to be snowy here. So now I'm at a little more than 1/4 tank. I dont know anything about fuel injection but I'll do plugs, and fuel filter and aircleaner..I already did cap and rotor. Thanks for trying to help me out.
