Common signs of failure / service requirement:

• Crossfire, backfiring or random-cylinder misfire

• Hard starting in damp or humid conditions

• Carbon tracking, burnt terminals or internal arcing

• Cracks, corrosion or green deposits inside the cap

• Rough idle and loss of power under acceleration
