Re: 97 3500 454 4x4 project
Good pick on the injectors.
Are you sure its not a bad/dying fuel pump? For a code reader, I use the TorquePro app on my phone with a bluetooth elm reader that plugs into the OBDII port. My 454 'burb with 4.10s gets around 11.2mpg, back and forth to work. I did make 13.12mpg the other day running up the interstate to Iowa with a generator in the back at 72mph.
