So havent really driven my 7.3 in about a year and a half. Tried starting it and the batteries were just too far gone. Replaced the batteries turned truck over got oil pressure and truck was a little hard ti start. Once ut started it was smoking white smoke which I expected but ran good. Let it warm up and took it for a ride around the block. Was running fine then as I pulled into the driveway it was running rough and wouldnt accekerate oast 2200 rpms. Shut it off let it sit for a while started it up anf it idles fine started to accelerate and it starts acting like its missing and im getting white smoke out the exhaust. Anyone hzve any ides or should I run some new fuel with fuel system cleaner through it? Thanx in advance

 

that's the best place to start, then filters

 

old fuel too i bet.give her a few fresh gallons and a couple quarts of mercon atf and see how she likes it.
