You are not driving your Geo in a firing range and yet you could hear a sort of a firing sound. You start to suspect that the sound is coming just right under your Geo' hood but where exactly it could come from? The sort of a firing sound that you hear can be due to faulty electrical wirings in the engine particularly caused by defective Geo spark plug wires.
The Geo spark plug wires or ignition wires connects the spark plug to the ignition coil or distributor. Geo spark plug wires are designed to bear the high amount of electricity it delivers to the spark plug. The twenty thousand or more volts are being carried by the Geo spark plug wires from the distributor cap to the terminal of the spark plug. The electricity travels to the other end of the spark plug and creates a gap between the electrodes to produce the spark which ignites the fuel mixture. When the insulator in the spark plug wires breaks down it causes a rapid discharge of electrons across it thus, the spark is created.
Basically, the spark plug wires are made up of various layers of materials. The fiber core which can be found inside the spark plug wires carries the high voltage of electricity. Metallic wires were used in the older design of spark plug wires but it caused electrical interference with the radio and television reception. Some other spark plug wires have a locking connection at the distributor cap. The Geo spark plug wires are made of a conductive core and insulation. The conductive usually a carbon impregnated fiber or wire can be made from nylon to Kevlar while the insulation material is made of silicon rubber.
As you constantly drive your Geo, the Geo spark plug wires gradually wear. As it age, the conductive core develops cracks and the insulation gets brittle that lead to the deterioration of the Geo spark plug wires. Once your Geo spark plug wires become defective it will cause engine misfiring, damaging the spark plugs and a bumpy ride. Some of the causes of spark plug wires failures include breakage of wires inside the insulation due to vibration and corrosion at the connectors.
Spare your Geo from engine misfiring by making sure that your Geo spark plug wires are in perfect condition. Should there be a need to replace your Geo spark plug wires, Parts Train is just a click away from you. Parts Train has a comprehensive list of high quality Geo spark plug wires that perfectly fit into your Geo.
