Q: Engine misfiring.

You can usually identify an engine misfire by the distinct feeling and sound you get from the engine. A misfire is usually accompanied with a check engine light and if the misfire is critical, the check engine light will blink. Resolving the misfire requires that we determine the cause behind the misfire and which cylinder is doing the misfiring in your vehicle. Using an automotive scanner to communicate with the truck’s computer will point us in the right direction of which cylinder is misfiring. In most cases the repair is just a matter of providing your car’s engine with a routine tune up. A tuneup involves replacing the spark plugs, the ignition wires and, if equipped, the distributor cap and rotor. These are just the most common reasons why an engine experiences a misfire. It must be noted however that there are always uncommon reasons that could be at fault too. Faulty fuel injectors and vacuum leaks, as well as exhaust leaks, have been known to cause a vehicle to misfire. Due to engine misfires being caused by so many variables, and the solution varying just as much, it is always best to enlist the help of a certified mechanic to go over your vehicle with you and diagnose the reason of your misfire.
