What about the routing of the vac lines from where the IAB canister used to be. There should have been a Y connection where the vac supply for the FPR and IAB meet. What did he do with all that stuff? FPR should have remained connected to a vac source. No chance he switched the IACV and IAT plugs is there? That’ll fry the IAT immediately and it will run like ass.
