⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the engine to cool before opening the throttle body or working on the fuel system.

Symptoms

•Engine stalls when accelerating
•Rough idling before stalling
•Loss of power during acceleration
•Engine misfires
•Check engine light illuminated

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any stored trouble codes.
2
Inspect the fuel system for proper pressure and flow using a fuel pressure gauge.
3
Check the air intake system for blockages or leaks that could affect airflow.
4
Examine the ignition system components, including spark plugs and ignition coils, for wear or damage.
5
Inspect the throttle body for carbon buildup or malfunctions.
6
Evaluate the engine’s vacuum system for leaks that could disrupt air-fuel mixture.

Solution

Solution

1. Preparation

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

2. Address Fuel System Issues

Sub-step 1: Check fuel pressure using a fuel pressure gauge; it should be within manufacturer specifications (typically around 40-50 psi for Mustang).
Sub-step 2: If pressure is low, inspect the fuel pump, filter, and lines for clogs or damage. Replace any faulty components.
Sub-step 3: Ensure the fuel injectors are clean and functioning. Consider using a fuel injector cleaner or replacing them if necessary.

3. Clean or Replace Ignition Components

Sub-step 1: Remove spark plugs and inspect for wear. Replace any plugs that show signs of damage or excessive carbon buildup.
Sub-step 2: Test ignition coils with a multimeter to ensure they are operating within normal resistance values. Replace any faulty coils.

4. Clean the Throttle Body

Sub-step 1: Remove the intake duct to access the throttle body.
Sub-step 2: Use throttle body cleaner and a soft brush to clean any carbon buildup. Make sure to clean the throttle plate and surrounding areas.
Sub-step 3: Reassemble the intake duct securely.

5. Repair Vacuum Leaks

Sub-step 1: Visually inspect all vacuum hoses for cracks or disconnections.
Sub-step 2: Replace any damaged hoses and ensure all connections are secure.
Sub-step 3: Use a smoke machine or carb cleaner to detect any leaks while the engine is running.
