Here's why and how to find it:
* Engine Variations: Infiniti QX4s from 1999 likely came with a few different engine options. Each engine has its own unique firing order.
* Finding the Code: You need to identify the engine code to look up the firing order. You can find this code:
* On the engine block: Look for a metal tag or plate directly on the engine.
* In the owner's manual: Your owner's manual will list the engine details.
* Online resources: Websites like CarPart.com or AutoZone.com allow you to search by year, make, and model to find engine specs.
Once you know the engine code, you can search online for the specific firing order for that engine. Here are some places to look:
* Manufacturer's website: Check the Infiniti website for their service manuals or technical bulletins.
* Online automotive forums: Search forums like "Infiniti QX4 forums" or "Nissan Pathfinder forums" (the QX4 shares many components with the Pathfinder).
Remember: Be cautious when working on your vehicle's engine. If you are not comfortable with this type of work, it's best to consult a qualified mechanic.
