Thread: Trilogy Surging at part throttle

  1. #1

    Trilogy Surging at part throttle

    Well I've cleaned out my MAF sensor, and my Idle Air Valve, but now the Marauder starts to occasionaly surge on partial boost. By surge it sounds like it's applying more boost then letting off, then letting it on. Replaced the boost rubber part on the passenger side. Don't know what that is callled. Any help...

    Sounds like mine when the factory fuel pump took its sweet time dying.
