Trying to Diagnose an Engine Misfire?


Ignition components are normally very reliable. But, with any electronic part, things can fail. To understand the range of induction coil failures, it is crucial to understand how various auto coils function as well as how overheating fits into the equation. When voltage from your automobile's battery passes through the ignition coil to the plugs, it ignites the fuel mixture in every cylinder. Regardless of the type of ignition system, all coils are exposed to a lot of heat with the repetitive surge of power passing through them. A failed automotive coil can cause problems such as an engine misfiring or stalling of the engine when you try to pull off.

With time, the spike of voltage and the repetitive heat produced by the generation of spark can wear out the insulation between the primary and secondary wrap. Whether your coil is the older canister type or your truck uses a coil-per-cylinder ignition system, an automotive coil is a mechanism consisting of a ferrous core wrapped in primary and secondary windings. The proportion of turns between the windings determines the coil's highest output voltage. When a coil-on-plug begins to have problems, the performance of the engine will be affected due to the reduction in spark in one or several cylinders.

As the insulating layers in the plug wires begin to weaken, it makes it much harder for the spark to flow from the coil pack to the cylinder where combustion happens. But, prior to your replacing the ignition wires or coil-on-plugs in your vehicle, it is important to perform a detailed inspection of the ignition system, including the vehicle's plugs. First, if the warning light in your car or truck is displayed, it is crucial to have a mechanic check the displayed codes to decide if coil and plugs are the reason. Age and miles traveled are natural enemies to your vehicle's ignition wires and coil pack.

If it's time to change the plugs, spark plug wires, ignition coil or coil pack in your automobile, E3 ignition products are built to meet or exceed OEM specifications. You can visit the "Where to Buy" page of this website or purchase products online at shop.e3sparkplugs.com. Just remember, replacement ignition coils need to be the same kind and have the exact primary impedance as the original ignition. When you change the failing ignition coil, erase the codes with OBD2 code reader. Most franchised auto parts dealers allow you to borrow a reader if you use it at the store. Don't forget to crank the engine to see if the code comes back.
