I couldn't agree more about fuel system flush is nothing but an unneeded service bordering on scam, just like a transmission flush. ..unless your fuel system got severely contaminated, so much so the filter won't pass fuel. Even then a flush won't clean injectors if some debris has found it's way to the nozzle. Can you please answer Tom's questions? That will help us

The light has never been on before, the truck has 101,000 miles and I was convinced it would be good PM. The codes are P0420 and P0430
