2000 excursion 7.3 erratic power

Ok this is hard to explain. On my ex I can be driving down a dirt road and hit a bump and it is like someone pulled the power out of the motor, then the next bump it all comes back. All this time I have not moved my foot. I have hooked the AE up to it and parameters look good. I have an edge flash programmer in it but it does not seem to matter if it is in stock or programmed. Also when I go to take off from a light or stop sign sometimes it will surge real bad 2 or 3 times. It is driving me crazy. It will stay consistent but the bumps seem to be what flares it up. Doesn't seem to do it at highway speeds or on cruise. Any help pointing in the right direction is appreciated

Sounds like a loose connection somewhere in the fuel control circuit. If you have a good quality scanner that allows you to perform a "wiggle" test and obviously any DTC's.... that would be a good place to start.

Check all fuses and relays in both the central junction box under the dash and the box under the hood ( in front of driver's side firewall).

A common area often overlooked is the fuel injector wiring harness that runs along the top of the cylinder heads. You'll want to pay particular attention to the connectors located at the top inboard surface of each cylinder head where the valve covers mount to the heads. These connectors see a lot of heat and over time get brittle and saturated with oil. They will loosen up and create a faulty connection.
Hope this helps.
