Engine CHYA

Symptoms:
- Rough idling or stalling shortly after starting
- Loss of power or hesitation during acceleration
- Increased fuel consumption
- Check Engine Light (CEL) illumination
- Occasional misfires or uneven running

Diagnosis:
- Inspect ignition coils and spark plugs for wear or damage, as these are common failure points causing misfires.
- Check for vacuum leaks around intake manifold and hoses, which can cause rough idling and poor performance.
- Scan for fault codes related to fuel injection, ignition timing, or sensor malfunctions.
- Examine the throttle body for carbon buildup affecting airflow.
- Test the fuel pressure and fuel injectors for proper operation.
- Verify the condition of the camshaft and crankshaft position sensors, as faults here can trigger CEL and performance issues.

Fixes:
- Replace worn or faulty spark plugs and ignition coils to restore smooth combustion.
- Repair or replace any damaged vacuum hoses or intake components to eliminate leaks.
- Clean the throttle body to ensure proper airflow and throttle response.
- Replace faulty sensors such as camshaft or crankshaft position sensors as needed.
- Service the fuel system by cleaning or replacing injectors and ensuring correct fuel pressure.
- Reset the ECU after repairs to clear fault codes and allow relearning.

Prevention:
- Follow regular maintenance schedules, including timely spark plug and ignition coil replacement.
- Use quality fuel and perform periodic fuel system cleaning to prevent injector clogging.
- Regularly inspect and replace air filters to maintain clean airflow.
- Avoid prolonged idling and aggressive driving to reduce engine stress.
- Keep the engine bay clean to prevent dirt and debris from causing sensor or component issues.
- Address any warning lights or performance changes promptly to avoid escalation.
