My truck jumps or runs roughly... I don't know how to describe it. It's like if someone dumped the clutch. It's a manual, it does it through all gears, so I don't think it's the transmission. I was thinking it might be the fuel pump, but I don't know how to diagnose it. I've got an 83 with the cologne v6. I think it's just got the engine driven fuel pump, no electric, but I'm not sure. Either way, I think it could either be the fuel pump or maybe a vacuum leak. At least that's from what I've read.
