I am changing out the spark plugs for the first time on my 1995 4R, I have been procrastinating since i got it 2 months ago because I know its a *****. But when I pulled out the #2 spark plug it was a pain in the ass to get out because it was rusted in and I am affraid to put the new on in with all the rust in there any tips on doing it without F...ing it up!
