I have a 2004 ford f350 i did the egr delete on it and after it i started and it ran perfectly fine for a good 20 seconds then it shut off. but it will start right back up everytime. If i start it and rev it up to 1500-2000 RPM's it will stay running. i did the wiggle test and that did nothing...

OK I just recently bought a 05 f350 with the 6.0. Just yesterday i started the truck and it died:look: So then i cranked it again and while cranking i held the throttle and truck started and then ran fine. Well then i found out this is going on everytime when i start it. What happened to this...
