Hi Everyone... Sorry if this topic has been done to death, I was unsubscribbed for a while. It's time to tune up my 98 GLX (60K miles). Rather than take it to a dealer, who will mearly replace the plugs and then charge me a fortune... I've decided to do it my self. Any suggestions on the best plug to use? Also... on where to get the special spark plug tool? Anything else I should check/replace? Thanks John L
