Cylinder 1 Misfire Detected
that injector is on the front of the motor on the passenger side, you will have to remove the fuel injection control module to get to that one. ur going to need some pry bars to get the inejector out. make sure the copper washer comes out with the injector. lube up the orings with engine oil and put a new copper washer and put the new injector in.
Fuel injector bracket bolts are tightened down to 22lb ft.
the injector supply high pressure line is tightened down to 30lb ft.

Prior to removing the fuel injector pipes, use compressed air to blow any debris from between the injector line and fittings. Wipe the fittings clean of debris.
Spray lithium grease, GM P/N 12346293 or equivalent, between the fuel injector line and fittings to assist in containing any debris during removal.
Remove the fuel injector pipes. NOTE: DO NOT use compressed air to clean debris from the fuel injector inlet after the fuel line is removed. Using compressed air can allow debris to enter the fuel injector inlet and damage the fuel injector.
