Should I replace spark plug wires with my spark plugs?
That’s because spark plug wires aren’t actually made of wire. That’s why it pays to replace your spark plug wires before they wear out. We recommend changing them during spark plug changes (whenever your owner’s manual recommends, usually between 60,000 and 100,000 miles).
How do you wire a spark plug wire to a distributor?
Here are basic steps on how to connect spark plug wires in the correct order:
- Get the owner’s manual for your specific car.
- Check for the distributor rotor rotation.
- Locate the number 1 Firing Terminal.
- Connect the number 1 Firing Terminal to the first Cylinder.
- Connect all the spark plug wires.
Can a bad distributor cause a 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.

Where are the spark plugs on a General Motors engine?
The placement of each spark plug wire on the distributor cap is directly correlated to the engines firing order. For example; a standard V-8 General Motors engine has eight individual cylinders. However, each cylinder fires (or reaches top dead center) at a specific time for optimal engine efficiency.
When do you need a new spark plug?
If your vehicle has recently developed a stumble, or misfire, restoring its performance may require new spark plugs, new spark plug wires, or a new distributor cap and rotor. These are common maintenance items that should be replaced regularly on most vehicles.
How does a spark plug wire work on a car?
The high voltage must be conducted from the ignition coil to the spark plug, where two electrodes facilitate the spark from the high potential difference. The spark plug wires’ work is to conduct that high voltage from the ignition cable to the spark plug.
