96, intake, exhuast, and TS chip with swamp diesel programs and 164,000 mi. When I take off and get on it from the start, sometimes it will stumble and then take off. It does it on all settings of the chip, any ideas what to check for?

 

My first thought would be clean the fuel pressure regulator screen. Take the fuel filter out, and look in the little hole on the drivers side of the bowl on the inside with a mirror. You should see a nice shiney screen. If not, take q-tip sticks (no cotton) and gently clean all the crud off of it. That should get you going. If not, check fuel pressure. It's a start.
