back it out till it stops, spray some lube at the threads, then turn it back in and out, working it in and out till it comes out, or the threads may rip out of the head.

On the topic of spark plugs, what plugs will work best for my 3.8 series II N/A engine? I know there are posts about this, which I have read, but they say "stock" plugs as far as I know. Well mine have been replaced with what I believe are cheap plugs at a corner service center, so I'm not sure what I should look for. Will replacing then with the recommended plugs get me more power/efficiency? I'm not very impressed with mine compared to our impala with the 3.8 with original plugs at 109k miles.
Also I tried to pull my plug wire boots off the plug to get a look, but the metal clip in the boot tore off...Never ended up being able to see what was in it, didn't care much after the spark plug wire failure.

02Navyblue: Wrong forum. But REDCOMPG has the right of it: The guy at the parts counter will hand you the correct plugs if you just ask for "stock."
