Ignition cylinder sticking
 

The ignition cylinder on my 1991 Z sticks when I try to turn it all the way back to remove the key. Whats the best way to lubricate it? I have bypassed VATS.

Try some graphite spray lubricant. Most hardware stores carry it in a small aerosol can with the little red tube for getting into locks. Spray it where you put the key in. Keep a rag around where you spray it to prevent it getting on your interior.
