So I have a a weird problem with my 7.3. After leaving my truck over night when I start it the next day the truck starts and idles for a sencond or two. Then it dies out like it is running out of gas. When I restart it it starts fine but idles rough. If I rev it up to 1000 rpm and hold it for about a minute then it cleans up and smooths out. The rest of the day the truck runs great. No smoke no hard start new motor new pcm and rosewood injectors adrenaline hpop and d66 turbo. Any ideas what would be causing this?
Thanks for your help.
