#3 plug
 

How do you replace #3 plug without jacking engine?

With a swivel adapter for your ratchet. Or by using a wrench on the end of your socket.

The easiest way is by removing the tire and do like TheRandom1 said, use a wrench on the end of a spark plug socket.

On my ZR2 I didn't need to do that however. Just slid the socket over the plug, and slid my swivel in it and went.

you have to either cut the socket on one end or move the steering collum....its not easy to get to otherwise.

I was able to buy a spark plug socket with a swivel built in from AutoZone for a few bucks. With that swivel socket and some extensions, it was a piece of cake. I didn't have to do a thing to the steering column.

Good Luck!
