I have 1998 5.7 vortec. Started running real rough. Trying to die when coming to a stop. Now starts up and runs rough , place in gear and dies. Sounds like air blowing or sucking right before it dies. Fuel pressure around 60 , changed fuel filter, plugs. distributor cap, still doing it. Any suggestions?
