My car hasn't been running very well and I was wondering how this could be. I started troubleshooting and found that there wasn't any battery problem there wasn't any alternator problem and there wasn't any starter motor problem. Then I learned that the spark plugs were from the original factory when it was new. I replaced the 30-year-old spark plugs put in new ones and now she runs like a brand-new car.

Volvo for life. New parts included

Original spark plugs.
