Why is there no spark in my ignition?
An ignition module requires some type of external input in order to activate. If your vehicle stalls unexpectedly during operation and will not start again, it is likely because of loose or corroded electrical connections in the ignition module. In this case, check the switch, clean oxidized terminals, and replace broken wires if necessary.

What does a cylinder 4 misfire code mean?
P0304 is a cylinder specific misfire code, which means that Cylinder 4 is misfiring and causing the code. An important thing to understand when finding the location of Cylinder 4 is that it’s going to be the 4’th cylinder in the firing order of the vehicle, and not the 4’th cylinder that you might see when looking at the engine.
Where to find cylinder 4 on Chevy Spark?
An important thing to understand when finding the location of Cylinder 4 is that it’s going to be the 4’th cylinder in the firing order of the vehicle, and not the 4’th cylinder that you might see when looking at the engine. The P0304 trouble code will trigger the Spark’s service engine soon light. The vehicle itself may begin to run rough.

What do you need to know about cylinder misfire?
This means you need to remember the engine load, throttle position, RPM and of course, road speed. For a cylinder misfire problem, you need to change components, such as coils, spark plugs, etc. to isolate the root cause of the misfire. Also, make sure you jot down the other codes, as misfire can be caused by a malfunctioning component or system.
Can a worn out spark plug cause a misfire?
Combine a worn out spark plug with lean air/fuel mixture, and that 80kV is going to find an easier path to ground. Even the best insulator boot can’t contain it indefinitely; at first the spark will leak through the boot to the valve cover only during acceleration]
What is the error code for a misfire?
When a misfire occurs in the engine, it will automatically set the check engine light and show a number. The last digit of the number signifies the specific cylinder at fault. For example, if it’s cylinder #1 that is having trouble firing, the Error Code will be P0301.
What is the error code for cylinder 4 misfire?
Error Code P0304: Cylinder 4 Four Misfire Detected. Error Code P0304 is described as Cylinder #4 Misfire Directed, which means the vehicle’s computer has detected an engine misfire, specifically with the fourth cylinder.
What happens to the PCM when a cylinder misfires?
You already know that when a cylinder misfires continuously, the PCM will turn off the dead cylinder’s injector to avoid sending gasoline straight into the catalytic converter. However, it doesn’t remember the misfire, as it discovers the misfire anew each time the engine is started.
What causes a misfire on a coil on plug?
When the engine cools off overnight, the fuel in the rail cools and condenses, leaving a small pocket of vapor at the highest point in the rail, right next to injector No. 1. Naturally the misfire clears up quickly as the rail fills with fuel, and there’s no reason to chase this problem any further (how could you possibly fix it?).
Error Code P0304: Cylinder 4 Four Misfire Detected. Error Code P0304 is described as Cylinder #4 Misfire Directed, which means the vehicle’s computer has detected an engine misfire, specifically with the fourth cylinder.
What causes a misfire on an ignition coil?
It is also possible that a failed ignition coil can cause damage to the engine computer, or ignition control module. Commonly an engine computer detects a misfire by measuring the changes in crankshaft speed. This change in speed can be caused by a combustion event that is happening early, late, or not at all.
Why does my Mercedes engine misfire when I change the spark plug?
Keep this in mind especially if you change the spark plugs in your Mercedes and you are still getting an engine misfire. Fuel pressure can cause engine misfire as well.

How does the OBDII system work for a misfire?
The OBDII system can identify the cylinder (s) that are not contributing their normal dose of power and set a corresponding DTC. A P0303 DTC, for example, would indicate a misfire on cylinder number 3. If the ODBII system is unable to identify a specific cylinder a P0300 random cylinder misfire DTC will set.
