ok, I got my truck running like a top yesterday. Timed it just right, ran smooth and strong. Last night I ran out of fuel (gas gauge broke) which was no big deal cause it was just sitting there idling till it was warm enough to leave my g/fs house. Well they gave me a fuel jug they had in a shed that had about 1/3-1/2 of "gasoline" in it that they use for the lawn mower.. well it wasnt enough... So i ran to the station and got some more gas, got it started and now it pops like a SOB at idle. Off idle is fine as far as I can tell it seems to run ok... I didn't change anything on the truck, just put gas in it, so my only idea is that the gas was bad.... what do you guys think?
