my 2001 lightning is missing at full throttle if i slowly push the gas pedal its fine but if I romp on it is has a miss all the way through the acceleration
the truck is bone stock except for a exhaust and i have a programer but have it set to stock i all so changed the fuel filter just because i dont know when it was changed last
ANY THOUGHTS

Its either fuel, or spark. Start testing them.
