560sel dies when let off the gas

over the weekend i put new fuel injectors in my 1990 560sel, it runs great on the highway but when i let off the gas to coaST it dies just like that. what do i need to check? air fuel mix, timming, or idle control module? i am stumped and frustrated.

you may have disconnected a hose under or around the intake.
