It's been a while since the last tune up.So far I've only gaped/replaced the spark plugs and air filter.I plan to get new spark plug wire set,upper and lower radiator hoses and clamps.I'm by no means an ace mechanic but I have decent mechanical skills and tools.I want to do a good through tune up job on my 91 6 cyl with auto tranny.What else should I do/replace.
Change to a K&N stock replacement air filter,as will flow more air & life time warranty. Also @ this time change to a larger plug wire for less resistance & better spark!
