I don't drive the truck very often, maybe 250 or 300 miles a month. When I give it gas and it bogs down, I've noticed that the tach will read higher rpm - as it should when I give it more gas - but the engine sounds like it has completely stalled. Then when I ease off the throttle the engine will start firing again.
