Are they P.T.D injectors?
Expert:  John Vieira replied 1 year ago.
Don't the injectors set to 72 inch pounds? On the outer base of the cam?
Customer: replied 1 year ago.
Our service manual stipulated setting the injectors to .187. We solved our problem before we received any replies from justanswer.com by setting the injectors 60 in lbs.
