Engine Misfire

The Engine of any Mechanical Device be it automobile or any other is solely responsible for its functionality, Engines are designed to function effectively as long as proper combustion takes place, for this combustion to be said to have taken place there has has to be an exact ratio of fuel and air mixture, if by para venture the air fuel ration isn't accurate enough that brings us to the issue on ground engine misfire, what is engine misfire?

An engine misfire simply is a situation where an
engine fuel ratio mixture is interrupted either by defective components or other related factors,
Engine misfires most times constitute a great deal of problems to car owners most notably fuel consumption,.

CAUSES OF ENGINE MISFIRE
Engine misfire could be caused by several components in an engine ranging from ignition components to fuel supply components and all of that but to streamline these causative factors we ll take a close look at three of these likely components


SPARK PLUGS



spark plug

The spark plugs can easily be seen as the primary ignition component in an automobile engine come to think of it if other components are found to be in place and the spark plug is missing certainly combustion will not take place, a defective spark plug has all the tendency to trigger engine misfire, this small but vital component which links the ignition system to the engine proper becomes defective when the center electrode, copper core or the suppressor is unable to supply enough spark through the ground electrode to the piston, this will certain render the affected piston ineffective which ultimately leads to misfire

When faced with engine misfire issues one of the first components to inspect should certainly be the spark plug.


OXYGEN SENSORS

To a layman this could sound ridiculous but in actual sense a defective oxygen sensor could trigger engine misfire, with the advent of technology in cars of today every function of the modern day car is monitored using a sensor, an oxygen sensor is a form of sensor that monitors the amount of fuel mixture, this small but vital components usually located along the exhaust manifold has the tendency to go bad and when it does the resultant effect usually progresses to engine misfire, as earlier stated the primary function of an oxygen sensor is to monitor the fuel mixture if it runs rich or lean, lets assume the fuel mixture is stable and the engine running proper, a faulty oxygen sensor could send a lean signal to the on board computer to dump more fuel in the combustion chamber which can ultimately lead to engine misfire or vise versa.

Several reasons why an oxygen sensor can go bad is as a result of age , mishandling by technicians or maybe electrical problems.

FAULTY AIRFLOW METER

The airflow meter or air intake sensor as its popularly known these days is an engine component that primarily measures and monitors the quantity and speed of air that goes into the engine ,a defective air flow meter has the tendencies of causing an engine to misfire, this component can either go bad or certainly wear out on its own.


STUCK IDLE CONTROL VALVE

The basic function of an idle control valve is to regulate the or maintain a balance idle speed for engine this small component is usually found very close to the throttle body can easily cause an engine to misfire if it gets stuck with dirt which is usually the case, to correct this annomality all that is needed is to carefully remove this compomemt, and clean up using a carburetor spray or cleaner as the case may be this should do the trick (for diys, though)

ELECTRICAL ISSUES
Cars of today are more of wires and sensors than actuators, faulty electrical short circuit or bad fuses can also trigger engine misfire most of these fuel management systems are all interconnected by wires and cables if these cables snap or have loose connectors these could easily trigger engine misfire which can only be corrected through physical inspection or diagnosis


Other related issues that could lead to engine misfire are clogged up fuel filter, blocked fuel line, bad fuel pump or even a faulty E.C.M (rain box)

What ever the case might be it is advised to allow your techman carry out a proper diagnosis when faced with engine misfire, because of its environmental and financial hazards/

a clogged up catalyst usually leads to grave engine misfire

1 easy way to know when you have a serious engine misfire, is that the check engine symbol flashes as against just staying on

What about faulty ignition coils?
