Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to prevent electrical shorts.
Gather tools and parts before beginning repairs.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect it for dirt or damage.
Install a new air filter that matches OEM specifications.
Reassemble the air filter housing cover and reconnect the battery.

3. Fuel System Inspection

Locate the fuel pressure test port on the fuel rail.
Connect a fuel pressure gauge and turn the ignition on (do not start).
Check the fuel pressure reading against manufacturer specifications.
If pressure is low, replace the fuel pump or filter as necessary.

4. Ignition System Service

Remove the spark plugs using a spark plug socket.
Inspect the spark plugs for wear, carbon buildup, or damage.
Replace any faulty spark plugs with new ones that meet OEM specifications.
Reinstall the spark plugs and ensure they are torqued to the correct specifications (typically 15-20 lb-ft).

5. Exhaust System Check

Inspect the exhaust system for any visible damage or blockages.
Check for any leaks in the exhaust manifold and connections.
If a blockage is found (e.g., clogged catalytic converter), replace the affected component.
