Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety before working on electrical components.

2. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, spark plug socket, gap tool.
Remove the ignition coils by unscrewing the bolts and lifting them off.
Use the spark plug socket to unscrew each spark plug.
Inspect the spark plugs for wear; replace any that are worn or fouled.
Set the gap of the new spark plugs to specifications (consult repair manual).
Install the new spark plugs and torque them to the manufacturer's specifications.

3. Check and Repair Exhaust System

Tools Required: Wrench set, exhaust clamp tool.
Visually inspect the exhaust system for cracks or holes, especially around the manifold and muffler.
Tighten any loose connections or clamps.
If damage is found, replace the affected section of the exhaust system (e.g., muffler, pipe).

4. Inspect Air Intake and Replace Filters

Tools Required: Screwdriver set, vacuum cleaner.
Remove the air intake duct and inspect for blockages or damage.
Replace the air filter if dirty or clogged.
Reassemble the intake duct securely.

5. Check and Adjust Fuel Pressure

Tools Required: Fuel pressure gauge.
Locate the fuel rail and connect the fuel pressure gauge.
Turn on the ignition (without starting the engine) to check the fuel pressure; compare it to manufacturer specifications.
If pressure is low, inspect the fuel pump and replace if necessary.
