To locate the ECU on a 2003 Toyota Corolla, you can refer to this YouTube video: https://www.youtube.com/watch?v=glHF3DRpZro. Various engine issues may arise, such as loose gaskets that should be promptly tightened, oil leaks that require immediate fixing, and spark plug malfunctions leading to engine problems. A critical concern is the risk of engine overheating, potentially causing car fires or explosions. Monitoring for excessive oil consumption is vital, and oil changes should be done promptly when needed. Air filters should be replaced every 15,000 to 30,000 miles, coolant changed every 60,000 miles, and spark plugs swapped out every 100,000 miles (or sooner for copper spark plugs, which should be replaced every 30,000 miles).
