I have a 94 chevy 3500 with a 6.5 turbo diesel. I was having a bad idle problem and it would shut down but when it warmed up but there was a check engine light when it happen so we put scanner on it well it did it so all solutions came back to the fsd module so i put a brand new 1 in so ran good after then the 2nd time driving it went to get on high and it started bogging like it was running out fuel but this time no codes or check eng. Light were do i go from here
