Hi, I have a bit of an issue with my truck, It starts well, but seems to sputter as I dive, It is a standard,and in second gear ,it starts doing this it seems to be choking?or maybe not getting enough gas? I used some fuel injector cleaner and checked the plugs+wires[which are new] now I'm going after the fuel filter, any more suggestions? I need this truck good for mon. morn. thanks Jb
