Correction
The customer sates the check engine light is on.
Connected a scan tool and found code P0300 - Random/Multiple Cylinder Misfire Detected. Performed a visual inspection of the air intake system and found no obvious concerns. Inspected the ignition system but found no obvious faults. Attached a lab scope with an inductive ammeter to the ignition coil control circuit, ran the engine, and monitored the ignition coil primary amperpage waveform on the lab scope. The ignition coil primary amperage waveform monitored on the lab scope indicated the ignition coil was shorted.
Replaced the ignition coil, cleared codes, performed a road test and verified the vehicle operated properly. The check engine light did not illuminate and no fault codes returned.
