How do you replace a spark plug cable?
One by one, remove and replace the spark plug wires. By doing them one at a time, you will not have to worry about accidentally switching the wires. To remove an old cable, pull directly upward on the boot of the cable on the spark plug end, and then pull upward on the boot connected to the distributor cap or module.
Why is my car sputtering after new spark plugs?
It is possible for there to be a vacuum leak, a faulty oxygen sensor, a catalytic converter that is starting to show signs of failure, or even a possible problem in the fuel system. It will be necessary to do some further diagnostics to determine which system is causing the problem, and then figure out which part in that system is the root cause.
Where are the spark plug wires in a car?
Step 2: Locate the ignition cables. The cables will be routed from the spark plugs on the top of the cylinders to the distributor cap or module that powers them. Step 3: Replace the cables. One by one, remove and replace the spark plug wires. By doing them one at a time, you will not have to worry about accidentally switching the wires.
What happens when the spark plug wire fails?
They do this because of a signal received from the computer module or distributor cap. If the ignition cable, or spark plug wire, carrying this signal fails, the operation of the engine becomes mistimed and under-powered. One or more cylinders will may misfire or weaken.
Why do I need to change my spark plug wires?
However, there are other factors that can play a role in the timing. Damage: It’s possible for spark plug wires to be damaged. If the insulation is compromised, or there’s an internal break, you’ll need to replace your wires even if it’s not yet time.

Why is my spark plug on my ATV not working?
Some older ATVs have problems with spark plug wires that connect to the spark plug. So if your spark plugs look good, that’s the next thing you’ll need to check. You will want to look to make sure the connection head is correctly attached to the spark plug wire, and that it hasn’t become corroded over time and use.
Do you need an ohmmeter for spark plugs?
You’ll need an ohmmeter for this, and you’ll need to know what the wires’ original resistance was. Test each wire and look for resistance levels higher than when originally installed, as well as higher resistance in individual wires (which indicates a failed wire).
