Default Spark plug issue, 94 LT1 6 speed

I took my car out today and was still in the neighborhood when I heard a loud bang and the car started missing and sounded like I had an exhaust leak. What I found was a spark plug came out. It's the last plug on the driver's side. I tried to put it back in. After two full turns it tightens up. I don't want to force it. Any suggestions? Ever heard of this before?
Thanks in advance.

Hi i recommend a tap with the spark plug thread to chase the damaged threads, hopefully its not too damaged the spark plug may have been cross threaded and not tightened fully.
Always make sure the spark plug is going in by hand, i always use my fingers for the first few turns to make sure then only tighten the last 1/4 turn with a ratchet.

Good luck
