What does a bad ignition coil sound like?

Engine misfiring will be seen in a vehicle whose ignition coils have failed. Trying to start the engine of such a vehicle will result in engine misfiring that sounds like a coughing, sputtering noise. When driving at high speeds, jerking and spitting will be seen in the behavior of the vehicle.

How do I test an ignition coil?

Connect your multimeter to the positive terminal or pin of your coil, and to the high output terminal that goes to the spark plug. Most ignition coils should have a secondary resistance falling somewhere between 6,000 to 10,000 ohms;however, refer to manufacturer specifications for the correct range.

What problems can a bad distributor cause?

Your car keeps stalling: A failing distributor can prevent adequate voltage from reaching the spark plugs. Since the engine needs that spark to run, a bad distributor can result your car stalling when it idles.

How do you test a distributor module?
