Affects Chevrolet Lumina Car, Monte Carlo · 1996–1997 — about 3K vehicles.
The hazard
On certain vehicles, the spark plug wires may be causing the Malfunction Indicator Lamp (MIL) to be illuminated, as well as causing rough idle and poor performance. These conditions may be due to a dielectric breakdown of the plastic extender piece at the boot joint of the spark plug wire. Correction: Dealers will replace all six spark plug wires with a new service spark plug wire assembly kit that is designed to be robust against dielectric breakdown failures.
