* Specific engine code needed: To determine the firing order, I would need the specific engine code of the Mitsubishi engine installed in your car. There were various Mitsubishi engines used in the 1985 Aries.
* Model variations: Even within the same year and model, there might be different engine options.
How to find the firing order:
1. Check your owner's manual: This is the most reliable source of information.
2. Locate the engine sticker: Look for a sticker on the engine block or near the valve cover. It often includes the engine code and firing order.
3. Consult a repair manual: A repair manual specific to your vehicle will have the firing order.
4. Search online: Use your vehicle's year, make, model, and engine code to search for information online.
Important note: The firing order is crucial for proper engine operation. Using an incorrect firing order can lead to misfires, engine damage, and poor performance.
