Change fuel filter. Check fuel pressures, should be about 13, and a special inline adapter is needed for this. If not fuel filter suspect fuel pump. Coworker just went through this.

Figured it out the egr was weak and would vacume test ok but when driving it it would suck I open so I blocked it off and runs great
