What happens when a distributor rotor goes bad?
A faulty distributor cap can cause your engine to stall. Voltage must be produced by the spinning distributor rotor for the engine to keep running. If the rotor does not rotate properly, the engine loses power and stalls out as you’re trying to drive. The longer you let this go on, the worse it will get.
What does a distributor rotor do?
Distributor caps and rotors are responsible for passing the voltage from the ignition coils to the engine’s cylinders in order to ignite the fuel-air mixture inside and power the engine. The coil connects directly to the rotor, and the rotor spins inside the distributor cap.
What happens when you have a bad distributor?
A faulty engine distributor won’t spark, which will either prevent the engine from starting or cause it a running engine to fail. The distributor also disburses current to the spark plugs initiating engine performance.
How long does distributor rotor last?
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.
Can a bad distributor cause loss of 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].
Can a bad distributor cause rough idle?
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.
What problems can bad rotors cause?
When rotors are warped or very worn, the contact between it and the brake pad can be imperfect. This sketchy contact results in vibration and shaking that can be felt through the brake pedal, steering wheel and even the car body.
What can bad rotors cause?
Warped and worn brake rotors may cause vibrations that may be felt in the brake pedals, chassis, or steering wheel. In addition, bad brake rotors may cause the brake pedal to pulsate or vibrate when pressed due to uneven brake discs.
What are the symptoms of a bad distributor rotor and cap?
Usually a faulty distributor rotor and cap will produce a few symptoms that alert the driver that service may be required. 1. Engine misfires Engine misfires can occur for a number of reasons.
Can a bad distributor cap cause an engine to stall?
This is normally one of the signs of your distributor cap going bad but can signify other problems as well. A faulty distributor cap can cause your engine to stall. Voltage must be produced by the spinning distributor rotor for the engine to keep running.

Some Common Bad Distributor Symptoms If your distributor is suffering some problems, here are the most common bad distributor signs: Squealing Noises: One of the very first signs that you will notice if your car has a bad distributor cap is a yelling or squealing noise.
What can a bad distributor O ring do?
