The way your 2003 Ford Explorer’s engine works is by firing the cylinders in a specific order, which is 1-4-2-5-3-6. When you’re facing the front of the car, you’ll find the first cylinder on the right side, at the front of the engine. It’s really important to get this order right.
If you don’t, your car might start to run rough, lose power, and use a lot more gas. So, if you notice your car is using more gas than usual or it’s not accelerating as fast as it used to, it might be time to give your engine a check-up. Right usage of this information will make your engine run better and use less gas.
There’s a lot more you can learn about how your car works, so keep exploring.
