Re: Sparkplugs, how often do you change yours?
i check my plugs about every 1000 miles or so, sometimes more often. If they look worn, replace. if they look good, check the gap, regap if necessary, and replace.
If they look bad at all, i'd say replace them. NGK's are only like $1.10 a piece.
I also recommend an engine tune up. distributor cap, ignition rotor, spark plug wires, air filter, oil & filter change, check/set ignition timing.
