Why do I need a spark plug gap?
Opening up the plug gap is an attempt to use a larger resistance value to force the spark that “jumps” the gap to a higher voltage level. If your ignition system is up to it, it really shouldn’t matter what temperature your engine is, unless you’ve got really bad mixture distribution problems in your intake manifold.

What are the symptoms of a narrow spark plug?
The symptoms of narrow gap include a noticeable (continuous) cylinder miss, hard starting if all the plugs have narrow gaps, rough idle and engine hesitation. A spark plug that does not fire, resulting from a narrow gap, will appear black or wet when inspected. The black or wet appearance indicates unburned fuel.
