Troubleshooting a faulty distributor can be a real headache. This guide will walk you through diagnosing and fixing car distributor issues, helping you get back on the road quickly. We’ll cover everything from the basics to more advanced fixes.
Understanding the distributor’s role in your car’s ignition system is crucial. It’s responsible for sending high voltage to the correct spark plug at the right time, ensuring smooth engine operation. When the distributor malfunctions, your car might experience issues like misfiring, rough idling, or even failing to start. So, let’s dive into how to fix a car distributor.
Identifying a Faulty Distributor
Several signs can point to a problematic distributor. These include:
- Engine Misfires: The engine might stutter or hesitate during acceleration.
- Rough Idling: The engine vibrates excessively when idling.
- Difficult Starting: The car might crank but not start.
- Reduced Power: The car might feel sluggish and lack power.
- Decreased Fuel Efficiency: You might notice a drop in your car’s mileage.
If you experience any of these symptoms, it’s time to investigate your car’s distributor. Don’t delay, as a faulty distributor can lead to more severe engine problems. Check out this helpful resource on how to fix a car that wont start if your car isn’t starting at all.
Checking the Distributor Cap and Rotor
The distributor cap and rotor are common culprits in distributor problems. Inspect them for cracks, carbon buildup, or damage.
- Remove the Distributor Cap: Carefully remove the cap, noting the position of the rotor and wires for reassembly.
- Inspect the Cap: Look for cracks, burns, or corrosion on the cap and terminals.
- Inspect the Rotor: Check the rotor for damage, such as a burnt or corroded tip.
If you find any damage, replace both the cap and rotor. They’re relatively inexpensive and easy to replace. It’s always best to replace both at the same time to ensure proper function.

Testing the Ignition Coil
The ignition coil generates the high voltage needed for the spark plugs. A faulty coil can cause a range of ignition problems.
- Locate the Ignition Coil: The coil is usually located near the distributor.
- Test the Coil’s Resistance: Use a multimeter to measure the primary and secondary resistance of the coil. Consult your car’s repair manual for the correct specifications.
If the resistance readings are outside the specified range, the coil needs to be replaced. A failing ignition coil can dramatically impact engine performance. Wondering what to do if your car doesn’t run before selling? Find helpful advice in our article: car doesn’t run fix before selling.
Inspecting the Distributor Wiring
Damaged or corroded wiring can also disrupt the distributor’s operation.
- Check the Wiring Connections: Carefully inspect the wiring connected to the distributor for loose connections, breaks, or corrosion.
- Clean or Replace Wiring: Clean any corroded connections or replace damaged wires as needed.
Faulty wiring can lead to intermittent issues that are hard to diagnose. Ensure all connections are secure and free of corrosion. Learn about fixing a car attenuator in our article on car attenuator fix.
