Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is turned off.
Gather all necessary tools and parts.

2. Replace Air Filter

Sub-steps:
1. Locate the air filter housing (usually at the front of the engine).
2. Unclip or unscrew the housing cover to access the air filter.
3. Remove the old air filter and clean any debris in the housing.
4. Install the new air filter, ensuring it fits securely.
Tools Required: Screwdriver or socket set (if applicable).

3. Replace Spark Plugs

Sub-steps:
1. Disconnect the battery to prevent electrical shorts.
2. Remove the ignition coil (if applicable) to access spark plugs.
3. Use a spark plug socket to remove old spark plugs.
4. Install new spark plugs, ensuring they are gapped correctly (typically 0.054 inches for most Ford engines).
5. Reconnect the ignition coil and battery.
Tools Required: Spark plug socket, ratchet, gap tool.

4. Repair Vacuum Leaks

Sub-steps:
1. Visually inspect vacuum hoses for cracks or disconnections.
2. Use a smoke machine or carburetor cleaner to detect leaks while the engine is running.
3. Replace any damaged hoses to restore proper vacuum pressure.
Tools Required: Smoke machine (if available), hose clamps.

5. Tire Pressure Adjustment

Sub-steps:
1. Check the tire pressure using a tire gauge.
2. Inflate tires to the manufacturer-recommended pressure (found on the door jamb or in the owner's manual).
3. Inspect tires for uneven wear or damage.
Tools Required: Tire pressure gauge, air compressor.
