1. Remove the engine harness, the throttle position sensor, the EGR valve, the pressure sensor, and all of the fuel injector connectors.
2. Remove the EGR valve and the EGR adapter.
3. Tape the EGR case holes shut to prevent the entry of foreign material.
4. Remove the cylinder head cover.
5. Alternately loosen the fuel injector terminal nuts a little at a time in sequence. Several loosening cycles should be required before the nuts are loose.
