    I have a 1980 mack em6 two stick. My truck does fine when I give it gas and shift gears but when I try to go slow or let off the throttle it starts jerking and hoping real bad but when I give it gas again it quits. So every time I let off the gas petal the truck bucks can anyone please help

    Place your right foot completely on the throttle pedal (no heel to floor), this gives you better throttle control at slow speeds and will eliminate the problem.
