Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Faulty Components

A. Ignition System

Tools Required: Socket set, torque wrench, spark plug socket.
Remove spark plugs using a spark plug socket.
Inspect spark plugs for wear and carbon buildup.
Replace any faulty spark plugs with OEM or recommended aftermarket parts.
Check ignition coils for proper operation; replace if faulty.

B. Fuel System

Tools Required: Fuel pressure gauge, basic hand tools.
Connect a fuel pressure gauge to the fuel rail to check for proper fuel pressure.
If pressure is low, inspect the fuel pump and fuel filter; replace as necessary.

C. Air Intake

Tools Required: Screwdrivers, pliers.
Inspect the air filter for dirt or clogging; replace if needed.
Check the intake manifold for leaks; repair any found.

D. Exhaust System

Tools Required: Visual inspection tools.
