    Before they replace injector #4 there was a code for injector 4, now besides the codes for the egr's there is nothing else

    The majority of the Problems are the wiring harness for the fuel injector itself not the fuel injector.

    As for the bad fuel milage, do the easy stuff first, check the front mount air intercooler for leaks, got to hold 30 pounds of pressure, only 3 pound drop in 30 seconds, any more then that inter cooler is bad,

    any leaks with the Tubes or the intercooler, can cause up to 2 mpg lost in fuel economy
