I have a 5 speed 2001 Ford ranger Truck. When I and changing the gears or just driving in 5th gear, the truck seems to jumps as though it's not getting the gas. I put injection bost and cleaner in the tank, yet it does the same. Sometimes it jumps badly.
Thanks,
Lewis

I have the same problem. So I changed the spark plugs, distributor, and spark blug wires. When I did I found that the spark plug in cylinder number 3 was soaked with fuel. So I change the fuel injector in every cylinder and that did it.
