Can bad spark plug wires cause backfire?
Unburned fuel then is allowed to pass into the exhaust system where it can backfire.
The same type of problem can be caused by a worn out or damaged spark plug wire.
A bad wire will make the spark’s travel difficult, weaken the spark, or simply push it into an adjacent wire or to ground, resulting in a backfire..
What are signs of a bad distributor?
Usually a faulty distributor rotor and cap will produce a few symptoms that alert the driver that service may be required.Engine misfires. Engine misfires can occur for a number of reasons. … Car doesn’t start. … Check Engine Light comes on. … Excessive or unusual engine noises.
Do high performance spark plug wires make a difference?
Is there a performance difference between different spark plug wires? … Performance wires will measure much less, such as 40 ohms per foot. This reduced-resistance allows the engine to start easier and will produce a smoother idle. There is some minor performance improvement with this lower-resistance rating.
What causes bad spark plug wires?
If there is any issue with the spark plug wires the engine spark can be disturbed, which can result in engine performance issues such as misfires, a reduction in power and acceleration, as well as a reduction in fuel efficiency. In severe cases bad cables may even result in engine stalling.
What are the best performance spark plug wires?

What are the symptoms of a bad spark plug wire?
When spark plugs wires fail, a host of engine problems can result.Rough Engine Idle. The most common symptom of bad spark plug wires is a rough engine idle. … Engine Miss. … Engine Hesitation. … Reduced Engine Power. … Engine Surging.
How good are Belden spark plug wires?
They are very good wires and I have never had any problems at all with my current set. I was just hoping they were still made here in the USA. I did find out the NGK plugs I plan to use are made in West Virginia.
What happens if you mix up spark plug wires?
Bundling of spark plug wires and wrapping them with tape, pulling them through metal tubes or dressing them tightly against the engine, may make them look neat but can cause serious voltage losses and/or crossfiring. Changing the routing from the original OEM routing can lead to early spark plug wire failure.
How much resistance should a spark plug wire have?
Question: How many Ohms of plug wire should be used? Answer: Usually between 10,000 and 12,000 ohms of resistance per foot of wire.
Should spark plug wires have continuity?
It should light correct? True. But be aware that the resistance of automotive spark plug wires can vary from about 40 ohms/ft to 10,000 ohms/ft depending on application. If you have the high-resistance wires, there is a chance your simple tester might not register continuity.
What’s better 7mm or 8mm spark plug wires?
8mm spark plug wires are a heavier gage wire than the 7mm type. However, there is more to it than just the difference in the thickness. The thicker wire has a thicker core. … A more robust core provides a lower resistance path for the power, thereby allowing more power to reach the spark plugs.
Can spark plug wires increase horsepower?
In short, yes, in some situations spark plugs can increase horsepower. … The theory behind spark plugs increasing horsepower is that by providing more spark to the firing tip of the spark plug, it will (and does) combust more fuel.
