The factory spark plugs in your Audi vehicle are responsible for creating the initial flash that allows the ignition to kindle the air-and-fuel mixture in the engine's combustion chamber.
How Spark Plugs Work
The spark plugs generate that flash, or spark, by shooting an arc of electricity across a gap between two leads. The gaps are precisely calibrated to deliver the ideal sparking needed to combust the mist of fuel and air.
If your vehicle uses diesel fuel, though, you don't have spark plugs. Instead, your engine is equipped with glow plugs. They ignite the mix
However, your GM vehicle may run on diesel fuel. In that case, you have glow plugs instead of spark plugs. These have a heating element in their tip, which ignites the mist thatÕs sprayed into the engine cylinder.
In time, however, your spark plugs may become less effective. That could be due to either corrosion or the gaps widening too far to produce effective sparking. Signs of trouble include:
- Uneven engine idling
- Misfiring engine
- Trouble starting your vehicle
- Your "Check Engine" light comes on
