I am a serial entrepreneur and a consumer advocate. When I’m not helping car buyers, I love working on ventures that have a positive impact.
If you're a car owner, you probably know how important it is to keep your vehicle running smoothly. One of the critical components of a car's ignition system is the distributor, which distributes high-voltage electricity to the spark plugs.
If the distributor isn't functioning correctly, it can cause a range of problems that can affect the performance of your engine and even prevent your car from starting altogether.
In this article, we'll take a closer look at the common bad distributor symptoms. We'll explore the most common signs that your distributor may be on the fritz and what can cause these symptoms.
We'll also discuss how to diagnose and address bad distributors so that you can keep your car running smoothly and avoid costly repairs down the line.

Bad Distributor Symptoms
You may notice a few telltale symptoms if you're experiencing issues with your vehicle's distributor.
There are several bad distributor symptoms that your distributor may be faulty, including high-pitched squealing, difficulty starting, and unexplainable shaking.
1. High-Pitched Squealing
One symptom of a faulty distributor is a high-pitched squealing noise from your engine. You can hear this noise when you start your car or rev the engine.
The noise may be particularly noticeable when the weather is cold, as cold temperatures can make the squealing more pronounced.
That noise stems from a problem with the distributor's bearings, which can wear out over time due to regular use.
If you're experiencing this symptom, it's vital to haven't your distributor inspected by a professional, as continued use can cause further damage to your vehicle.
2. Difficulty Starting
Another common symptom of a faulty distributor is difficulty starting your vehicle. This can manifest in a few different ways, including the engine cranking but not starting or the engine not cranking.
If your distributor is faulty, it may not deliver the necessary voltage to the spark plugs, preventing your engine from starting.
You may also notice that your engine is harder to start in cold weather, as the low temperatures make it more difficult for the spark plugs to ignite the fuel.
If you're experiencing this symptom, it's essential to have your distributor inspected by a professional, as continued attempts to start the engine can cause damage to other components in your vehicle.
3. Unexplainable Shaking
A faulty distributor can cause unexplainable shaking or vibration in your vehicle. This can be particularly noticeable when you're idling, as the engine may not be firing on all cylinders.
This can cause your car to vibrate or shake, which can be uncomfortable and potentially dangerous if left unchecked.
If you're experiencing this symptom, it's essential to have your distributor inspected by a professional, as a faulty distributor can cause other components in your engine to fail, leading to more severe issues down the line.
Can You Drive With a Bad Distributor?
But that's not all - a faulty distributor can also harm other parts in your engine compartment, which could lead to more costly repairs down the road. For example, it could cause your catalytic converter to get too hot and fail, which is not cheap to replace.
So, getting a bad distributor taken care of as soon as possible is best to keep yourself and your wallet safe. Don't risk getting stranded on the side of the road or having to deal with major engine repairs – just get it fixed.
What Causes a Distributor To Go Bad?
If you're experiencing issues with your vehicle's distributor, several potential causes could contribute to the problem.
Three of the most common causes of distributor problems are wear and tear, carbon buildup, and corrosion.
1. Wear and Tear
One of the leading causes of distributor problems is wear and tear. Over time, the various components of the distributor can become worn out, affecting its ability to distribute high-voltage electricity to the spark plugs.
This can cause various symptoms, including difficulty starting, misfires, and reduced performance.
Some parts that can wear out over time include the distributor cap, rotor, and bearings. If your vehicle is older or has high mileage, it's more likely to experience wear and tear on its distributor.
2. Carbon Buildup
Another potential cause of distributor problems is carbon buildup. Carbon can accumulate on the distributor's rotor and cap, affecting its ability to conduct electricity.
This can cause various symptoms, including misfires, reduced performance, and difficulty starting.
Carbon buildup is often caused by running an engine that's too rich, which can create more carbon deposits.
It's essential to have your engine tuned regularly to prevent carbon buildup and other issues affecting your distributor.
Corrosion is another potential cause of distributor problems. Over time, the distributor and its components can become corroded due to exposure to moisture and other elements.
This can affect the distributor's ability to conduct electricity, which can cause a range of symptoms, including misfires, difficulty starting, and reduced performance.
Various factors, including moisture and road salt exposure, can cause corrosion. Regular maintenance, such as cleaning and greasing the distributor, can help prevent corrosion from causing problems.
Effects of a Bad Distributor
If you're experiencing issues with your vehicle's distributor, it's essential to address them promptly, as a bad distributor can cause a range of effects that can affect your vehicle's performance and potentially cause damage.
Two of the most common effects of a bad distributor are catalytic converter heating and engine damage.
1. Catalytic Converter Heating
One of the main effects of a bad distributor is that the catalytic converter can heat up.
The catalytic converter is an essential component of your vehicle's exhaust system and is responsible for converting harmful pollutants into less toxic gases before they enter the atmosphere.
If your distributor is faulty, it can cause the release of unburned fuel into the exhaust system, which can cause the catalytic converter to heat up. That can damage the converter, reduce performance, and increase emissions.
If you're experiencing this symptom, having your distributor inspected and repaired promptly is essential to prevent further damage to your vehicle.
2. Engine Damage
Another potential effect of a bad distributor is engine damage. If the distributor is not functioning properly, it can cause a range of issues that can affect the engine's performance and potentially cause damage.
For example, a faulty distributor can cause misfires, which can lead to damage to the engine's cylinders and other components.
It can also cause the engine to run too rich or too lean, which can cause damage to the fuel injectors and other components. If you're experiencing these symptoms, it's important to have your distributor inspected and repaired promptly to prevent further damage to your engine.
How To Fix a Car Distributor Problems
If you are experiencing problems with your car distributor, such as difficulty starting the engine, misfiring, or backfiring, your best option is to replace the faulty distributor. You should replace the distributor cap and rotor if they show signs of wear and tear.
To fix the distributor problem, you will need to remove the distributor cap, disconnect the wire plugs, and remove the faulty distributor.
You can install the new distributor and connect the wires to the different engine spark plugs. Additionally, you will have to join a wire to the ignition coil.
Once the new distributor is in place, it is crucial to set its timing to match the specifications of your engine. This ensures that the spark plug fires at the correct time, allowing the engine to run smoothly.
Replacing a car distributor can be complex, so it is best to take your car to a qualified mechanic.
They can diagnose the problem and install a new distributor, ensuring it is appropriately timed and connected to the engine. This will help to avoid any further issues with the distributor and keep your car running smoothly.
A bad distributor can cause various issues affecting your vehicle's performance and leading to more severe problems.
It's vital to keep your distributor well-maintained and address any issues promptly to avoid costly repairs and potential damage to your engine.
Common bad distributor symptoms include wear and tear, carbon buildup, and corrosion; regular maintenance can help prevent these issues.
If you suspect your distributor is not functioning well, it's best to have it inspected by a professional mechanic who can diagnose the issue and recommend the appropriate repairs.
By taking care of your vehicle's distributor and staying on top of maintenance, you can ensure that your car runs smoothly and reliably for years.
