Filled gas tank on way to work this morning with same gas/station I always use. Every time I stopped the truck after that it would rev up and lurch forward. Its like a wild horse and I am afraid I might not be able to control it. I have to take it out of gear (auto tranny) until getting ready to go again but since there is a lot of stopping at lights and in commuter traffic I am worried. Could it be bad gas? Ideas would be appreciated. Its scary and this is the first time its ever done this.

Thanks,
Norman
