Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to ensure safety during repairs.

2. Address Fuel System Issues

Sub-step 1: Test the fuel pump's operation.
- Tools Required: Fuel pressure gauge.
- Instructions: Connect the fuel pressure gauge to the fuel rail. Turn the ignition to the "ON" position without starting the engine and check the pressure reading against manufacturer specifications (usually around 35-50 PSI).
Sub-step 2: Replace the fuel filter if clogged.
- Instructions: Locate the fuel filter, relieve fuel pressure, disconnect the filter, and install the new one, ensuring proper orientation.

3. Inspect and Replace Ignition Components

Sub-step 1: Remove and inspect spark plugs.
- Tools Required: Socket set.
- Instructions: Remove spark plug wires, use a socket to take out the spark plugs, check for wear or fouling, and replace if necessary (NGK or Denso brands recommended).
Sub-step 2: Check ignition coils.
- Instructions: Visually inspect for cracks or damage. If necessary, replace faulty coils with OEM parts.

4. Check Air Intake and Vacuum Leaks

Sub-step 1: Inspect the air filter and intake ducts.
- Instructions: Remove the air filter and inspect it for dirt or blockages. Replace if dirty.
Sub-step 2: Use a smoke machine or carburetor cleaner to check for vacuum leaks.
- Instructions: Apply smoke around vacuum hoses while the engine is running; if the idle changes, a leak is present. Replace damaged hoses.
