i got the truck 2 months ago and all its been is problems from the start . i though i had fixed every wrong with the truck but it seems to never stop . i have never had any problems with it stalling out or sputtering until it started to become colder out . every morning i would start it up with no problem and drive it a few blocks and then it would start to sputter . i made it to school and i talked to my auto teacher and he said that it was the choke not opening . after that i went to class and came back at lunch and it ran fine for a hour . the i brought it back home and parked it , and then it started to snow . after the snow stopped a few hours later i moved it back in to the driveway . when i parked it in the driveway it started to stutter. not bad at first but after a few mins it was stalling out the engine . so i went under the hood and pushed the choke open , but at that time it only made it worse and was barely running . at this point i have no idea what to do about this problem and would like to get it fixed before it becomes really cold out , so that i came not stuck at the side of the road .
