Can a bad distributor cause rough idle?
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.
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].
What makes distributor cap go bad?
One of the reasons a new distributor cap works so well is that there is no carbon in the cap. The carbon conducts electricity, which can cause a misfire to the wrong plug or arcing between several plugs at once. By keeping the cap clean and looking for damage during engine maintenance, the cap will last longer.
Can a distributor cause misfire?
your engine is misfiring: if the distributor isn’t providing enough juice to the spark plugs, it can cause your engine to misfire, which typically feels like the engine is stumbling. it’s usually caused by incomplete combustion. typically, a failing distributor will cause a misfire on all cylinders.
What problems can a bad distributor cause?
In comparison with modern cars and their solid-state ignition systems, the distributor has to be one of the most infernal parts of an older engine. If not regularly checked and maintained, it can cause all kinds of problems, like poor starting, misfiring, low power and, er, being stuck on the side of the road.
How often do distributors go bad?

What causes a car to shake while idling?
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.
What causes a car to sputter and idle rough?
A rough idling engine can be caused by spark plugs or spark plug wires. Spark plugs use the electrical current received from ignition coils to ignite the air/fuel mixture within the combustion chamber. A plug that is damaged or installed incorrectly can result in fuel being burned at an inconsistent rate.
Why does my car feel like it’s losing power?
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.
Can a bad distributor cap cause a car not to start?
If the distributor cap is not working as it should or is not firmly on, your car may not start. This is because the essential spark needed for combustion is not being delivered. Without the spark being delivered to the spark plugs, the engine won’t run.
