Your left side tapping noise is most likely a burnt #4 exhaust gasket. Exhaust leaks sound different on different makes of cars. In the DeLorean an exhaust gasket leak can sound very much like a valve tap. The lack of air flow is probably a defective AC Mode Switch. The rear wing on your DeLorean is more show than effect. When you consider the rear mass of the car (engine, body, and frame weight combined) it is unlikely you would feel any aerodynamic effect from the rear wing. BTW: my "D" has a high rear wing and I have never felt any influence on the cars handling or feel. If you notice any strange effects from the rear of the car I would suggest you check the condition of your trailing arm bolts (parts manual 5/3/0 #25).
