Hey guys. I finally got my car back from the tire place (they put in a new gas tank) and everything semmed to be fine. Two days later, I am driving around and all of a sudden the car starts to vibrate when the rpm's hit around 1500-2000. When I take my foot of the gas, the shaking and vibrations immedialtey stop and usually don't happen again unless I stop at a light or stop sign and accelerate from the stop. Is there any way that the place screwed something up when they put in the new gas tank?? I was thinking it could be the tranny mounts, but I'm just taking a stab. Any information would be greatly appreciated!! Thanks, Andrew
