Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, fuel pressure gauge, multimeter, and basic hand tools.
Ensure the vehicle is parked on a level surface, and the engine is cool.

2. Address Air Filter

Open the hood and locate the air filter housing.
Remove the screws or clips securing the housing cover.
Take out the air filter and inspect it for dirt and debris.
Replace the air filter with a new one if it is dirty.

3. Fuel System Check

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the ON position (do not start the engine) to check fuel pressure.
Compare the reading with the manufacturer's specifications.
If pressure is low, inspect the fuel pump and filter for proper operation and replace if necessary.

4. Transmission Fluid Inspection

Locate the transmission dipstick.
Pull the dipstick, wipe it clean, and reinsert it into the tube.
Remove the dipstick again and check fluid level and condition (should be bright red and clear).
If the fluid is low or dirty, drain and replace with the manufacturer-recommended transmission fluid.

5. Spark Plug and Ignition Coil Replacement

Remove the engine cover if applicable.
Disconnect the ignition coil connectors and unscrew the coils from the engine.
Remove the spark plugs using a spark plug socket and inspect for wear.
Replace with new spark plugs and reinstall ignition coils.

6. Exhaust System Inspection

Visually inspect the exhaust system for any visible damage or rust.
Tap on the catalytic converter gently to check for any rattling sounds that indicate blockage.
If blockage is suspected, replace the catalytic converter.
