Your 2004 Nissan Altima’s spark plugs fire in a specific order: 1-3-4-2. The first spark plug is near the front timing cover, then the others follow in order: 3, 4, and 2. It’s important to keep this exact order for your car to run smoothly.
If the order is wrong, your car might have problems like rough idling, using more gas, and not being as powerful. This 1-3-4-2 order is also found in some engines of cars like the Honda CR-V and Toyota Camry.
Keep reading and you’ll learn how to find the cylinders and fix any issues with the firing order yourself.
Quick Navigation
Key Takeaways
- The 2004 Nissan Altima’s spark plugs fire in the order of 1-3-4-2. This means the spark plugs ignite one after the other in this sequence.
- Spark plug ‘1’ is found at the front, close to the timing cover.
- If the spark plugs don’t fire in the correct order, the car might run unevenly and use more fuel.
- If you set the spark plugs to fire in the right order, the car’s engine will run more smoothly and use less fuel.
- Other cars, like the Honda CR-V and the Toyota Camry, also have their spark plugs fire in the 1-3-4-2 order.
Understanding 2004 Altima Firing Order
The firing order of a 2004 Nissan Altima is a way of explaining how the spark plugs in the engine ignite. It’s a pattern that goes like this: 1-3-4-2. Basically, this is the order in which the spark plugs fire up to make the engine run smoothly and efficiently.
The ‘1’ in the sequence refers to the first spark plug that fires up. It’s located at the front of the engine, near a part called the timing cover. After that, the third spark plug (‘3’) fires up, then the fourth one (‘4’), and finally the second one (‘2’). This cycle keeps repeating to keep the engine running well.
It’s a good idea to know this firing order. It can help your car run at its best, keep it from wearing out too quickly, and get the most out of your gas. It’s an important part of taking care of your car.
Symptoms of Firing Order Misfire
When your car’s firing order is not right, you might experience a few clear signs such as your car not running smoothly when idle, using more fuel than usual, or feeling like it’s not as powerful. These signs often point to misfires, which needs to be investigated and fixed.
| Signs | Possible Reasons | How to Fix |
|---|---|---|
| Car not running smoothly when idle | The firing order is not correct | Check and change the firing order if needed |
| Using more fuel than usual | Misfires in the system that starts the car | Check the system, do any needed maintenance |
| Feeling like the car is not as powerful | The engine is not working well because of misfires | Check the system that starts the car, make any needed changes |
Cylinder Identification and Similar Engines
Knowing where the cylinders are in your Nissan Altima can help you figure out and fix any problems with the order in which they fire. It’s important to know that this car has the same 1-3-4-2 firing order as many other engines. The first cylinder is at the front of the engine, near the timing cover. If your engine isn’t running smoothly, this might be the problem. It’s crucial that the spark plugs are in the right place, as this determines the firing order and how well your engine works.
Engines that are similar, like in the Honda CR-V, Toyota Camry, and Subaru Forester, also have a 1-3-4-2 firing order. If you know about these similarities, it can make it easier to figure out and fix problems, helping you get back on the road faster and with less trouble.

Conclusion
Understanding the firing order of your 2004 Nissan Altima – which is 1-3-4-2 – can help your car run smoother and use less fuel. If your car is misfiring, idling roughly, or using a lot of gas, it might need a tune-up.
It’s also important to know where the number one cylinder is. This firing order is the same for other common cars like the Honda CR-V, Toyota Camry, and Subaru Forester.
