- Verify coolant temperature sensor operation to avoid incorrect fuel mixture

Fixes:
- Replace worn or fouled spark plugs and faulty ignition components
- Repair or replace cracked or leaking vacuum hoses
- Clean or replace clogged fuel injectors
- Replace faulty sensors triggering engine warning lights
- Change timing belt as per manufacturer’s recommended interval (usually around 60,000 miles)
- Flush and replace engine coolant to maintain proper temperature regulation
- Perform ECU reset after repairs to clear fault codes

Prevention:
- Adhere to regular maintenance schedule including timely oil and filter changes
- Use quality fuel to prevent injector clogging and carbon buildup
