Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery before starting work.
Ensure the vehicle is on a level surface and secure with wheel chocks.

2. Address Air Filter

Remove the air filter housing: Use a socket set to unscrew the clamps and bolts.
Inspect and replace the air filter: If dirty or clogged, replace it with a new one.

3. Fuel System Inspection

Check fuel pressure: Use a fuel pressure gauge. Compare readings with manufacturer specifications.
Replace the fuel filter: If clogged or showing signs of wear, follow proper procedures to replace it.

4. Ignition System Maintenance

Remove spark plugs: Use a spark plug socket to take them out.
Inspect and replace: Check for wear; replace with OEM-equivalent spark plugs.
Check ignition coils: Use a multimeter to test resistance; replace if faulty.

5. Transmission Fluid Check

Inspect transmission fluid: Remove the dipstick and check the level and condition (should be red and clear).
Change fluid if necessary: Drain and refill with manufacturer-recommended transmission fluid, ensuring proper torque on the pan bolts.

6. Vacuum Leak Inspection

Visual inspection of hoses: Check for cracks or disconnections.
Use a smoke machine or carburetor cleaner: Apply around suspected areas to identify leaks.
