deposits on contacts had to be scraped off
how often should a distributor cap be changed? My truck has 208000 miles. thanks on 1996 Toyota Tacoma
If the plugs and the rest of the ignition system is good order and not requiring a higher amount than normal Kilovolts to jump the spark plug gap, the distributor cap if OE quality will last !00,000 good quality Denso cap lasts longer than a cheaper knock off.
