03 Cadillac Escalade EXT p0200, Injector circuit fault and p0300, random misfire. Inspected wiring on bank 2 and found injector 4 had a splice wire. Checked the rest of the harness and no other splices found. Don't we all hate rodents nesting in your engine bay.

Customer had a fuel leak from their generator. Gaskets internally were old and brittle. Ordered some new ones and it is good to go.
