    I have a 2002 F250 7.3, the truck runs awesome with 275,000 miles on it. The problem I'm having is when I start it I always let it warm up for 10 - 15 mins. But lately when I drive it everything is good until I put it in reverse then it stalls out and usually dies but it starts right back up with no issues and this only happens when put into reverse. All my investigations are leading to the idle air control valve. Am I going on a wild goose chase? Thanks for any help you can give me.
