Some of the most common reasons include wear and tear over time. The distributor is also prone to developing problems because of the harsh environment it is located in. However, before we delve more into bad distributor symptoms, it is prudent you first understand how a distributor works.
Since the distributor rotor and cap can go bad over time because they are located in a harsh environment, it is important to know the symptoms this part will give off before it completely fails. Signs you need your distributor rotor and cap replaced include: The Check Engine Light comes on.
The ignition coil converts the low voltage electricity into high voltage power in timed pulses. … That moves other distributor parts that cause the ignition coil to pulse, and sends the electricity down each spark plug wire in order. The power travels down the spark plug wires to the spark plugs and causes sparks.
When any changes are made to the engine of a car, the ignition timing is adjusted accordingly. If not, you could experience several problems with your engine with improper ignition timing like knocking, hard to start, increase fuel usage, overheating, and reduced power.
Bad spark plugs, fouled-up plug wires or a cracked distributor cap can cause spark loss, while compression loss — in which too much of the air-fuel mixture flees a cylinder before going bang — commonly arises from a leaky exhaust valve or a blown head gasket [sources: B&B; O’Reilly].
The distributor cap are tasked with passing voltage from the ignition coils to the engine’s cylinders through the spark plug wires and plugs themselves to ignite the air and fuel mix. A failing distributor cap will result in rough idle because the voltage is not being sent to the plugs at the proper time, or at all.
The distributor cap, rotor and spark plugs could make it longer, and were often replaced at the 30,000-mile (48,280-kilometer) tune-up. Spark plug wires held out the longest, with a recommended change at around 90,000 miles (144,841 kilometers).
Replacing the distributor cap and rotor at the same time should be completed every 50,000 miles, regardless of whether or not they are damaged. If your vehicle does not put on a lot of miles every year, it’s also a good idea to replace them every three years.
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.
As a general rule, replacing a distributor will cost between $89 and $123. This price includes the cost for parts, usually between $39 and $59, and the cost for labor hours, usually between $50 and $64.
When your spark plugs are performing as they should, your engine sounds smooth and steady. A fouled spark plug causes your engine to sound rough while idling. You might also feel the vehicle vibrating.
A bad spark plug may cause your engine to sound rough while idling. The vehicle-encompassing, jittery sound will also cause your vehicle to vibrate. It can indicate a spark plug problem in which a cylinder misfires only while idle.
If the ignition coil does not have spark, it’s time to check its wires. Use a test light to check the continuity on the signal wire and power wire on the ignition coil. If both wires are functional but the coil fails to produce spark, the ignition coil or the ignition control module is bad.
Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
The plug which is pointing right at you provides power for the electronics inside the distributor (green box). This is low voltage power. To power the spark plugs, the distributor is powered from a coil through the cap.
Your vehicle may make some very strange noises if the distributor rotor and cap are malfunctioning – specifically because the cylinders will try to fire but fail. You might hear a tapping, clicking, or sputtering sound when the distributor rotor and cap are failing.
The most likely issue is a clogged fuel filter. … While the fuel filter is the most common problem with the fuel system and is the easiest to fix, a lack of power could also point to issues with the fuel line or the fuel pump.
There are many reasons why your vehicle may be losing power, especially when accelerating. Some of these common causes are: Mechanical problems such as: Low compression, clogged fuel filter, dirty air filter, clogged Exhaust Manifold. … Malfunction of actuators such as: Bad injectors, bad fuel pump, bad spark plugs.
While a shaky idling car can certainly feel like an earth-rumbling tremor, it can also indicate a problem with the engine. One common cause of shaking while idling can be loose engine mounts. … Alternatively, a car that shakes when idle may have faulty fuel injectors, worn-out spark plugs, or a bad timing belt.
An acceleration problem is usually the result of insufficient fuel, air, or spark during the combustion process. Worn-out spark plugs or the electrical cables attached to them are one of the most common causes of cars stuttering.
What to Look For: Rough idle, slow acceleration, sputtering or a lack of power on acceleration are all symptoms of a leak in the vacuum system. Faulty EGR Valve – The EGR valve is responsible for recirculating exhaust fumes back into the combustion system.
Faulty coils may cause the vehicle to experience misfires, a rough idle, a loss in power and acceleration, and a reduction in gas mileage. In some cases the performance issues may even result in the vehicle stalling.
When your engine cranks but won’t start or run, it could mean your engine is having trouble producing a spark, getting fuel, or creating compression. The most common causes are problems in the ignition (for example, a bad ignition coil) or fuel system (for example, a clogged fuel filter).
If the ignition switch fails while the engine is operating it may cut off power to the ignition and fuel systems, which will cause the engine to stall. Depending on the exact issue, the vehicle may or may not be able to be restarted a short while later.
