If your vehicle has the inline 4.2 ltr six cylinder ...... you don't have one. Spark is controled by the PCM and is distributed to the plugs via the coils attached to the top of each individual plug. This creates a highly efficient system that requires the plugs to be changed out at a 100,000 mile service interval.
