Pull the spark plug wire out of the top of the engine. When changing all the spark plugs, only work on one spark plug and wire at a time so that you don't end up mixing up the plug wires. This will mix up the firing order of the spark plugs. Connect the socket extension to the...
Bad spark plug wires can cause a decrease in engine performance, decrease fuel economy, and can even cause hard starting (a condition where it is difficult to start your vehicle when the engine is \"cold\"-hasn't run-for more than 12 hours), or stalling. Replacement spark plug wires can...
This rapid change in magnetic flux induces a high voltage in the secondary winding through electromagnetic induction. The voltage produced can reach tens of thousands of volts, and travel to the spark plugs through spark plug wires. As the high voltage jumps the spark plug gap, it ignites the...
You can measure the resistance of the spark plug wires with a digital multimeter to see if they are working properly. Each foot of a wire should have a resistance of 10,000 to 15,000 ohms. A higher resistance indicates bad wiring. Even a hairline rupture somewhere can cause a total failu...
These are just a few of the components and systems to check if you want to keep your car running its best: Keep your engine properly tuned. This means changing the oil, air filter and checking the fluids on a routine basis. It also means changing the spark plug, spark plug wires and ...
the center and four, six or eight wires (depending on the number of cylinders) coming out of it. Theseignition wiressend the charge to each spark plug. The engine is timed so that only one cylinder receives a spark from the distributor at a time. This approach provides maximum smoothness....
1. Engine Temperature Warning / Coolant Temperature Warning:an internal combustion engine requires fuel to operate, electricity to start and keep the spark plugs firing, oil to be lubricated, and coolant to transfer heat effectively. This warning light comes on for a variety of reasons, including...
Faulty Plug Wires: Damaged or worn-out spark plug wires can prevent the electrical charge from reaching the spark plug. Computer Problems: Modern cars rely on computers (Engine Control Units) to control various engine functions, including ignition. A malfunction here can disrupt the ignition process...
and may take them up high enough to make the side electrode function as a glow plug. And when that happens you have the white-hot electrode firing the mixture far too early, like an over-advanced spark timing but worse because the early ignition causes yet higher combustion chamber temperatur...
If a sensor or part is reading bad, be sure to visually inspect the wires coming out of that part, and verify conductivity with a multimeter. If electricity is reaching a certain spot in the wire, but not all the way to the sensor, that wire should be replaced. ...
