What OBD/trouble code are you getting?

After replacing electrical parts/sensors, it is good practice to reset the computer by disconnecting the battery for a while. Then taking the truck out for a drive so the computer can relearn parameters.

Still, post what OBD code you are getting.

 

i was getting P401 insuffent flow when vacum line is off the egr and P0402 when vac line is connected
