Error Code P0304 is a common error code which signifies a misfire issue with the engine’s cylinder, particularly the cylinder #4. An engine misfire means lack of combustion, which can be a result of many things, like bad fuel quality, low compression, lack of spark, or unmetered air entering the entering the engine.
Four cylinders sit on both the right and left sides of the engine, for a total of eight. To determine the location of parts on a car or truck or its engine with regard to left or right side, the accepted method is from sitting inside the car.
Secondly, what does code po304 mean? When the code P0304 is set in the Powertrain Computer, it means that the Misfire Monitor has detected more than a 2 percent variance in RPM between the firing of any two (or more) cylinders in the firing order. The Monitor wants to see a smooth increase or decrease in engine RPM.
Also asked, how much does it cost to fix a cylinder 4 misfire?
It depends on the cause. For example, if the misfire is caused by a bad on-plug ignition coil, which is quite common on many newer cars, the repair might involve replacing a bad coil and all the spark plugs. This could cost $300-$400 for a 4–cylinder engine or $450-$700 for a V6.
How are cylinders numbered on a 4 cylinder engine?
Numbering the cylinders based on their position along the crankshaft (e.g. 1-3-5-7 along the right side bank and 2-4-6-8 along the left side bank). This approach is typically used by V8 engines from General Motors, and Chrysler.
How do you find a cylinder number?
On an inline engine: the number one cylinder is located at the front of the engine, closest to the timing cover. On a V type engine: one cylinder head is slightly forward of the other, toward the front of the engine. Cylinder number one is the forward most cylinder in that bank.
What side is number one cylinder?
Which cylinder is number 2 on a 4 cylinder?
The numbers 5 and 7 cylinders complete that side up through the 8 cylinder series. Opposite the number 1 cylinder, on the left side of the engine from the pilot’s seat, is the number 2 cylinder. Moving rearward again, we’ll find the number 4, 6, or 8 cylinder, whatever the case may be.
How many cylinders does a v4 have?
Are spark plug wires numbered?
1 and the cylinders are numbered in series to the back of the engine. Install the No. 1 plug wire, followed by the No. 3 wire, which is the third cylinder back, then continue installing the plug wires clockwise.
Can you drive with a cylinder 4 misfire?
Driving with a misfiring cylinder is not safe under any condition. Now, if you are thinking what causes a cylinder misfire, well, it is the bad spark plugs or the imbalanced air or fuel mixture, which is responsible for the misfiring a cylinder.
Can I drive my car with a cylinder 4 misfire?
Is it Safe to Drive With a Misfiring Cylinder? An engine misfire can be caused by bad spark plugs or imbalanced air/fuel mixture. Driving with a misfire isn’t safe and can damage your engine.
What does misfire on cylinder 4 mean?
P0304 indicates that cylinder number 4 is experiencing misfires. A misfire occurs when an insufficient amount of fuel is burning in a cylinder. The efficient burning of fuel is essential to engine operation as the combustion of fuel is what provides the energy to power the engine.
How long can you drive with a bad spark plug?
You can typically get 80,000 miles on them before they need replacing. But if you notice any of these symptoms, it’s time to get your spark plugs checked out with an engine tune-up. Continuing to drive with worn out or damaged spark plugs can ultimately cause engine damage, so don’t put it off.
Can a bad fuel injector cause a cylinder misfire?
Engine misfires and decrease in power, acceleration, and fuel efficiency. A faulty fuel injector can cause the vehicle to experience misfires, a loss in power and acceleration, a reduction in fuel efficiency, and in severe cases can cause stalling or prevent the engine from running at all.
How do you fix an engine misfire?
Method 2 Fixing Air and Fuel Misfires Use unrelated error codes to help narrow down the cause. Find and seal any vacuum leaks. Disconnect the fuel injectors one at a time and look for a change. Test your fuel system if the injectors seem fine. Replace the fuel injector if its not working.
