stalling/ bogging problem solved

My 94 Jimmy (155K miles) was stalling both in idle and while driving. Also bogging- feeling like it wasn't getting enough gas. All intermittently. Had new fuel pump and relay, computer, major tune-up, EGR and spider cleaned. 3 mechanics couldn't solve the problem, finally found one who found a short in the EGR harness. He replaced a section of it and repaired the connector. It drives great now.
Judging from these boards, stalling is a common problem in old Jimmys, so this might be a solution for those who are going through the torment of dealing with it. Good luck to all.

Thanks for the info...and I will check the erg electrical next... :o)
