Injector number four. Get car in air. Safely. Pull the injector rail (hoses, etc). Injector comes out from below. Get the book for this procedure. Takes 1.5 hour. Also replace the rubber PVC elbow at the top of the engine. If original, guarantee it is collapsed. You are welcome. Unless you want to replace the muffler, door regulators, compression hinges, etc. P>S> intake manifold won't take care of that tapping noise -- these cars have roller lifters that don't like any dirt. I would tell you how to find the one bad lifter but I need to go reprimer the jeep.
