I have 98. 5 Auto 3/4 ton ..... when on a trip, I stop, refuel, and then the truck runs very poorly ... Starts right away, idles fine, but has no power, smokes -- white / blue smoke when stepping on the accelerator, bucks and shakes the whole truck. I thought it might be water in the fuel, but draining some fuel out did not help. This only happens when I'm on a long trip, if I fill up when just driving in town, there are no problems.
Any ideas??????
