What MAP sensor is it running?, if it is still a factory 1bar sensor then make sure that is set to 94.4

Thanks, I believe its the factory one, its a delco unit. But this one is hooked up through a vacum hose and is hanging just behind the right valve couver. Shouldn't in be plugged directly to the intake? I blew on the little hose and it seems like it has a crack somewhere. I just cant see it, I think I might have to take off the intake to get it fixed up! ugggrh
