Why Is My Dodge 4.7 misfiring.?

Engine misfire happens when one or a couple of cylinder is not going to work successfully. It should scale back the facility generated by the car engine.

Figuring out the precise cause for engine misfiring is a bit difficult. However as soon as you determine the precise trigger, it will likely be simple so that you can resolve it.

The underlying points would be the cause why your Dodge 4.7 is misfiring.

#1.Unhealthy Sparkplug

The spark plug is integral in burning air-fuel combination contained in the combustion chamber. It ignites the air-fuel combination and produces energy which is critical to run an engine. 

Therefore ought to at all times stay clear. The electrodes must also stay in good situation for correct combustion.

If there aren’t any misfire codes, then essentially the most possible cause for misfiring is the soiled spark plug.

But when the spark plugs are fouled or grow to be soiled with time, it will likely be in a position to ignite the air-fuel combination accurately, ensuing within the engine misfiring.


  • Take out every spark plug and examine totally.
  • If the sparkplug seems apart from brown or tan coloration, then it signifies there may be some situation with the sparkplug.
  • If it seems moist, it’s due to oil or coolant leakage.
  • The spark plug wires can worn out with time. So, when you discover any worn wires, then substitute them.
  • Previous spark plugs are often worn out with time. In case you have not modified the spark plug for years, substitute it. The price of the spark plug is between $20 to $25, which isn’t a lot excessive.
  • Verify the gaps between the electrodes and examine them with the automobile guide.
  • The distributor cap can develop cracks with time in order that the engine can misfire randomly.

#2. Points In Ignition Coil

The battery voltage ranges from 6 to 12 volts which is inadequate to create sparks within the sparkplug and ignite the air-fuel combination. There comes the significance of the ignition coil. It acts as an induction coil which helps in changing battery voltage into a lot greater voltage in order that the spark plug can generate sparks.

It consists of a tender iron core on which there are major and secondary windings. The first windings are hooked up exterior to the secondary winding in order that it may well dissipate a lot warmth.

The secondary windings have nearly 21,000 turns and are totally insulated, so they can not are available another contact. At any time when the first windings obtain energy, the present is induced, creating magnetic flux. Consequently, excessive voltage is generated within the secondary windings. 

One a part of the secondary winding is related to the distributor. The distributor distributes the voltage generated within the secondary winding to the spark plug in each cylinder.

However when these windings get broken with time, then the engine could trigger a random misfire. Moreover, if the distributor doesn’t work accurately, it impacts engine efficiency and misfiring.


You will need to take away the ignition coil and check it with the ohmmeter. If there’s a discontinuity between the terminals, there’s a chance of broken windings. The ignition coil can fail on account of extra temperature, vibrations, or due to air trapping.

#3. Head Gasket Is Leaking

The head gasket is a vital part in an inner combustion engine. It acts as a seal between the engine block and cylinder head. 

The work of the pinnacle gasket is to forestall the oil and coolant from getting into the combustion chamber. In different phrases, you’ll be able to say that it seals the air-fuel combination contained in the combustion and doesn’t enable any outdoors fluid like coolant or oil to enter inside it.

There are numerous head gaskets like multilayer metal, composite, and copper. The most typical sort of head gasket seen within the majority of the car is multilayer metal.

However the head gasket bears extra stress and temperature fluctuations. So it may well have leakage and at last trigger a misfire on cylinders.

When the pinnacle gasket leaks, the coolant enters the combustion chamber. You’ll visualize white smoke from the tailpipe. Moreover, this smoke is in no way good for the catalytic converter.


In case you discover any leakage within the head gasket, then it’s higher to seek the advice of the mechanic and substitute it if required.

#4. Blocked Gas Injectors

A gas injector is an electronically operated valve. The work of the gas injector is to produce the pressurized gas to the combustion chamber. One can find a gas injector on the inlet valve of every cylinder in order that it may well spray straight into the combustion chamber.

The electromagnet will transfer the plunger and open the valve each time the injector is activated. The valve will enable the nozzle to spray gas within the type of mist in order that it may well simply burn within the combustion chamber. The quantity of gas that must be supplied to the combustion chamber is managed by ECU.

However the gas injectors can get soiled with time. The carbon can get deposited on gas injectors, and therefore it may well malfunction with time and thus leads to an engine misfire.


You might want to clear the gas injectors to do away with the answer.

#5. Defective Gas Stress Regulator

If the gas injector provides an excessive amount of gas contained in the combustion chamber, it’ll make the combination wealthy and badly have an effect on the engine’s efficiency. 

Equally, if the gas injector provides little gas, the combination turns into lean and can hamper engine efficiency. So the air-fuel fixture must be set proper for the correct working of the engine.

The gas is provided from the gas pump o the gas strain regulator. The work of the gas strain regulator is to produce pressurized gas into the gas injector in order that it may well spray gas contained in the combustion chamber.

If the system requires extra pressurized gas, the gas regulator will provide extra gas contained in the combustion chamber. But when the gas strain regulator malfunctions, the engine begins to misfire. Moreover, you’ll observe black smoke coming from the tailpipe.


In case you discover gas leakage on the gas strain regulator, there may be some situation. Take your car to the closest mechanic, who will totally examine the gas strain regulator and, if required, substitute it.

#6. Incorrect Air Gas Combination

Incorrect air-fuel combination within the combustion chamber is one more reason the car engine can misfire.

The faulty oxygen sensor primarily causes it. It’s often situated on the exhaust system of the car. The work of this sensor is to find out the presence of oxygen within the exhaust and supply data to the pc(ECU).

The ECU additional regulates the quantity of air-fuel combination that must be despatched to the combustion chamber. If the exhaust gases comprise a excessive share of oxygen, it is called a lean combination. 

But when the exhaust gases comprise much less share of oxygen, then it is called a wealthy combination.

O2 sensors don’t require loads of upkeep like gas filters. However soot cake can construct up on the oxygen sensor with time and therefore trigger engine misfire. 

When the oxygen sensor doesn’t work accurately, it sends flawed data to the ECU, and thus, it leads to an incorrect gas combination within the combustion chamber. It badly impacts the engine efficiency. 

The opposite signs of a failing oxygen sensor embody:

  • A rotten egg odor from the engine.
  • A lower in acceleration.
  • A discount in engine energy.


You may clear the oxygen sensor if it has gone grime. However whether it is badly broken, it’s good to substitute it with a brand new one.

#7. Faulty mass air circulation sensor

The work of the mass air circulation sensor is to measure the mass circulation fee of air getting into the combustion chamber and ship the knowledge to the ECU. The ECU will alter the air-fuel ratio accordingly and helps within the clean working of the engine.

However the mass circulation sensor can get broken with time. It’s due to fixed publicity to air filled with mud, particles, grime, and fumes. 

Failure of the mass air circulation sensor could make the air combination both too lean or too wealthy, which might badly have an effect on the engine efficiency and trigger engine misfiring.

Probably the most prevalent signal of a faulty mass air circulation sensor is the test engine gentle illuminating on the dashboard. Your car will even jerk and launch black smoke from the tailpipe.


Clear the mass circulation sensor if it has gone soiled. However whether it is broken, then substitute it with a brand new one.

#8. Vacuum Leakage

Vacuum leaks are one more reason for which the engine can misfire. It could possibly happen due to worn-out gaskets or pipes.


A vacuum leak means a small gap in some engine elements, together with gaskets and pipes. It permits an uncontrolled quantity of air to enter and exit and thus creates issues for the engine. Your engine may even misfire due to this cause. 

So, you’ll be able to detect the vacuum leak by inspecting the pipe and gasket totally along with your hand. A hissing sound is without doubt one of the fashionable causes for a vacuum leak.

Exchange the vacuum line if it’s severely broken to do away with the answer.

#9. Water Pump Leakage

The water pump<span model=”font-weight: 400;”> is the primary part of the engine, and it helps forestall the engine from overheating. It helps in circulating the water and coolant to numerous components of the engine and retains them chilly.

The leakage of the water pump doesn’t straight trigger a misfire. However when the coolant enters the combustion chamber, the engine can misfire.


Restore the water pump and substitute it to do away with the answer if required.

#10. Timing Belt Subject

The timing belt<span model=”font-weight: 400;”> is a crucial part of an inner combustion engine because it helps rotate the engine’s crankshaft and cam. It even ensures that each engine cylinder will fireplace on the right time for the correct working of the engine.

It often includes high-quality rubber and is principally current on the engine entrance. A number of pulleys are related to the timing belt, which works to the crank and camshaft.

However the timing belt might be worn out with time. In case you hear a ticking noise from the engine, it may well likely be due to a timing belt situation.


Exchange the timing belt with a brand new one whether it is worn out.
