Model Years Affected: 1998, 1999, 2000, 2001, 2002

Average Mileage: 187,000 mi (179,000 mi - 202,000 mi)


On higher mileage vehicles, an engine misfire may develop and/or the Check Engine Light may illuminate due to a failed ignition coil. It is not uncommon to replace all the coils when the first one fails in order to prevent return trips to the repair shop.
