So I recently purchased a 88 bronco II 2.9 4x4 so far I love it but I'm having some issues and I'm stumped if I start my b2 and just throw it in gear after about a minute or two of driving it will sputter fail to maintain idle and die if I make it down the road it will act like it loses power or gas then comes back and does it again but if I start my b2 and let it sit there and idle for about 2 min it will try and die then come back and drive with no problem at all
