Chevy express running rough after fill up

Go to Advance or Auto Zone and have them run an obd scan on it and it will pin point why your light is on and could solve your problem. This is often done for free.

Could be a sticky EGR valve, or a large vacuum hose off or burnt.

the problem you are discribing would lead me to belive your fuel filter is clogged which is a simple fix 3 dollar part at any part store or on the worse hand your fuel pump itself could be weak you can open the gas tank cover and have another person turn the truck key to the on position without going far enough to start you will hear a faint whining noise if it is going bad or a louder noise if it is fine Good Luck

How about the air filter and the fuel filter. Either one of those could cause these syptoms. you could also have a weak fuel pump. But check the filters first and get back to me, Raz

Check your valve adjustment ( rocker arms ).
