Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool before beginning work.

2. Inspect and Replace Air Filter

Remove the air filter cover using a socket set.
Take out the air filter and inspect it for dirt and debris.
Replace with a new air filter (ensure it meets manufacturer specifications).
Reinstall the air filter cover and secure it properly.

3. Fuel System Inspection

Check fuel injectors for clogs; clean or replace if necessary.
Verify fuel pressure with a fuel pressure gauge; replace the fuel pressure regulator if readings are outside of specifications.
Inspect fuel lines for leaks; replace any damaged sections.

4. Exhaust System Check

Inspect exhaust pipes and catalytic converter for any signs of damage or blockage.
Replace any damaged components to restore proper exhaust flow.

5. Tire Pressure and Alignment Adjustment

Use a tire pressure gauge to check each tire and inflate to the recommended PSI.
If alignment is off, take the vehicle to a professional for adjustment.

6. Engine Oil Change (if necessary)

Drain the old engine oil using an oil wrench and replace with new oil as per manufacturer specifications.
Replace the oil filter to ensure clean oil circulation.
