What should I do if my ignition coil is dirty?
Cleaning the dirty EGR valve might be enough to resolve the situation. Otherwise, a low-cost replacement is all that’s needed. The ignition coil is essential to maintaining proper engine performance. It works in conjunction with the spark plugs to ignite the fuel/air mixture.

You may start with the spark plug, however, the ignition coil will need to be removed to access the spark plug so it is typically easier to start with the coil. Next you will need to test your car once again by data logging or scanning for codes.
Why are spark plugs important to the ignition process?
As the spark is created it burns the air and fuel mixture, which in turn drives the engines piston to produce power. As ignition coils and spark plugs play an essential role in the ignition process, old or faulty spark plugs or coils that generate a weaker spark may not be able to fully burn the air/fuel mixture.
