Solution

1. Preparation

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

2. Address Fuel System Issues

Sub-step 1: Remove the fuel pump relay and test the fuel pump operation using a fuel pressure gauge.
- Tools Required: Fuel pressure gauge, socket set.
Sub-step 2: Replace the fuel filter if it is clogged or if the fuel pressure is below specifications.
- Tools Required: Wrenches, replacement fuel filter.
Sub-step 3: Inspect fuel lines for leaks or damage and replace as necessary.

3. Inspect the Ignition System

Sub-step 1: Remove the ignition coils and inspect for cracks or carbon tracking.
- Tools Required: Socket set, torque wrench.
Sub-step 2: Replace any faulty ignition coils and ensure proper torque on the mounting bolts.
Sub-step 3: Check and replace spark plugs if worn or fouled.

4. Test and Replace Sensors

Sub-step 1: Use a multimeter to test the MAF and TPS for proper voltage and response.
- Tools Required: Multimeter.
Sub-step 2: Replace any malfunctioning sensors with OEM parts.

5. Vacuum Leak Inspection and Repair

Sub-step 1: Use smoke testing or a vacuum gauge to identify leaks in the intake system.
Sub-step 2: Repair or replace any damaged vacuum hoses or gaskets.
