Solution

1. Preparation

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

2. Fuel System Inspection

Sub-steps:
1. Locate the fuel pump and test the fuel pressure using a fuel pressure gauge.
2. If pressure is low, replace the fuel filter and/or fuel pump as necessary.
3. Check for clogged fuel injectors; clean or replace as needed.
Tools Required: Fuel pressure gauge

3. Air Intake System Repair

Sub-steps:
1. Remove and inspect the air filter; replace it if dirty.
2. Check air intake hoses for cracks or leaks; replace any damaged hoses.
3. Clean the throttle body using throttle body cleaner, ensuring smooth operation.
Tools Required: Throttle body cleaner, basic hand tools

4. Ignition System Repair

Sub-steps:
1. Remove spark plugs and inspect for wear or carbon buildup; replace if necessary.
