Re: 67 Malibu, Electrical Starter Problems, sometimes
Have you considered making up a test jumper for the switch? Try using that for a short while and see if the problem goes away. It doesn't sound like you are wiggling the shifter around to get the NSS to engage. Might be something else so maybe I'd try a jumper before replacing the switch. Be sure to have the car in park before starting it with the jumper in place.
