Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a flat, stable surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the existing air filter and inspect it for dirt and debris.
If necessary, replace it with a new air filter (ensure it meets OEM specifications).

3. Check and Replace Fuel Filter

Locate the fuel filter along the fuel line.
Relieve fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines and remove the old fuel filter.
Install the new fuel filter, ensuring correct orientation and secure connections.

4. Clean Throttle Body

Remove the throttle body from the intake manifold by unscrewing the mounting bolts.
Spray throttle body cleaner on the inside of the throttle body and wipe it clean with a lint-free cloth.
Reinstall the throttle body and torque to manufacturer's specifications.

5. Inspect Exhaust System

Check for any visible damage or rust on the exhaust pipes and muffler.
Use a pressure gauge to test for backpressure in the exhaust system.
If a blockage in the catalytic converter is found, replace it with a new unit.

6. Test Battery and Alternator

Use a multimeter to check the battery voltage; it should read around 12.6 volts when fully charged.
Start the engine and measure voltage at the battery; it should read between 13.7 to 14.7 volts indicating proper alternator function.
If the readings are outside this range, replace the faulty component.
