fuel filter has less than 5k on it and im running 2 gauge ground wires from my battery to my block and from my cylinder head to the body. ive been questioning the egr valve though. i recently swapped it w/ another one from the junkyard to see if it would solve my intermittent miss at idle and above 3,000 rpms, but it made my truck run worse so i swapped the stock one back on. but i believe that has to do w/ my 268 eb cam not providing enough vacuum to it.

the truck does start back up immediately afterwards but dies instantly unless i press the gas.
