Here's a breakdown of what's likely happening and what you can do:
What's going on?
* Ignition Coil: The ignition coil is a crucial component that transforms low-voltage battery power into the high-voltage spark needed to ignite the fuel-air mixture in the cylinders.
* Intermittent to Constant: The fact that the problem started intermittently and is now constant suggests the coil is nearing the end of its life. The internal windings are likely breaking down, leading to weak or inconsistent spark delivery.
* Click and Rough Idle: The "click" you hear is likely the sound of the coil attempting to fire, but failing to produce a strong spark. This causes the engine to run poorly, misfire, and potentially stall.
Troubleshooting and Solutions:
1. Test the Ignition Coil: A reliable mechanic can test the coil's output using a spark tester.
2. Replace the Ignition Coil: If the coil is faulty, you'll need to replace it. This is a relatively straightforward repair for a mechanic.
3. Other Potential Causes: While the ignition coil is the most likely culprit, it's worth considering other possibilities:
* Spark Plugs and Wires: Worn-out spark plugs or cracked wires can also cause misfiring.
* Distributor Cap and Rotor: These parts wear down over time and can disrupt spark delivery.
Important Notes:
* Safety First: When working on your car's ignition system, be very careful to avoid electrical shocks. Disconnect the battery before working on any components.
* Get Professional Help: If you're not comfortable working on your car's electrical system, it's best to take it to a trusted mechanic.
