Is the truck showing a SES light? If you do check your codes with a paperclip on the OBD port, if not it's more guessing. If your fuel pump is running with enough pressure and your injectors are firing fine, it could still be several other things. Try unplugging the vacuum line to the egr, that would rule out if the egr is at fault.
