each new plug to factory recommendations as stated in your shop manual. Ours
should beg gapped at .035. Shown here are different styles of feeler gauges

then remove the spark plugs. Check each plug as you remove it. Look for burned
electrodes or carbon and oil build up. These could be signs of additional problems.
