⚠️ Safety Warnings

Important safety information - read before proceeding

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

Symptoms

•Check engine light illuminated
•Engine stalling during acceleration
•Hesitation or lag in power delivery
•Decreased fuel efficiency
•Unusual engine noises when accelerating

Solution

1. Preparation

Gather tools and parts required for repair.
Disconnect the battery to ensure safety during electrical work.
Allow the engine to cool before performing any inspections.

2. Air Intake Inspection

Remove the air filter and check for dirt or blockages.
Inspect the intake hoses for cracks or loose connections.
Replace the air filter if it is dirty or damaged.

3. Fuel System Repair

If low fuel pressure is detected, replace the fuel filter and inspect the fuel pump.
Ensure all fuel lines are free from leaks or damage.
Reconnect the fuel lines and check for proper operation.

4. Exhaust System Check

Inspect the catalytic converter for signs of clogging or damage.
If any restrictions are found, replace the catalytic converter.
Ensure the exhaust system is securely attached and free from leaks.

5. Ignition System Maintenance

Remove spark plugs and inspect for wear; replace if necessary.
Test ignition coils for proper functionality using a multimeter and replace any faulty coils.
Reinstall components securely and check for proper connections.
