Need to know what engine you have.
Would need engine size to answer this.
The spark plug gap for a 1995 Monte Carlo z34 is.45 inches. New spark plugs come preset, however, and should not need adjustments prior to installation.
Depends on if (and how may tmes) the cylinder has been bored.
motorcraft only, call a real parts house for exact prt number. dont let auto zone tell u bosch will work in it.

May just be the spark plug cables need replacing, humidity may be causing this problem and affecting the spark.
