Affected Component

Engine

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the engine to cool before opening any components.

Symptoms

•Check engine light illuminated
•Engine stalling during acceleration
•Reduced throttle response
•Unusual engine noises (e.g., knocking or sputtering)
•Poor fuel economy
•Increased emissions

Diagnostic Steps

1
Scan the vehicle's onboard computer using an OBD-II scanner to retrieve any diagnostic trouble codes (DTCs).
2
Inspect the air intake system for blockages or leaks; ensure the air filter is clean.
3
Check fuel pressure using a fuel pressure gauge to ensure it meets manufacturer specifications.
4
Examine the ignition system components, including spark plugs and ignition coils, for wear or damage.
5
Inspect the exhaust system for blockages or leaks that could affect engine performance.
6
Verify the operation of the throttle position sensor (TPS) using a multimeter.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical shocks.
Allow the engine to cool before proceeding.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a screwdriver or socket set.
Take out the old air filter and inspect it for dirt and debris.
Install a new air filter (ensure it is the correct size for the S650).
Reattach the air filter housing cover and tighten screws securely.

3. Fuel System Check

Connect a fuel pressure gauge to the fuel rail's test port.
Start the engine and observe the fuel pressure reading; compare it against manufacturer specifications (typically around 30-50 psi).
If the pressure is low, inspect the fuel pump and fuel filter; replace if necessary.

4. Inspect Ignition Components

Remove the ignition coil cover if applicable.
Check each spark plug for wear; replace any that show signs of fouling or wear.
Test each ignition coil for proper resistance using a multimeter; replace any malfunctioning coils.

5. Throttle Position Sensor (TPS) Testing

Locate the TPS on the throttle body.
Disconnect the TPS connector and use a multimeter to check the voltage output while slowly moving the throttle plate.
If the voltage does not increase smoothly or is out of specification, replace the TPS.
