- A worn or broken distributor drive gear
- A worn or broken camshaft timing chain and gears
An intermittent may be caused by a poor connection, rubbed through wire insulation, or a wire broken inside the insulation. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems. If a repair is necessary, refer to Wiring Repairs in Wiring Systems.
