Thread: 112-578 Throttle Body

  1. #1

    Default 112-578 Throttle Body

    Just put the Dominator EFI system with a 112-578 throttle body on a 6.2L LS engine. Dyno came in at 700 plus, but they said they couldn't get it to idle. We're running a cable throttle linkage. Was just wondering if the idle needs to be manually set with the set screw on the drivers side, or with both one for front plates and Allan screw for back plate? Thanks.
