Engine knocking during startup can be caused by several factors, including low oil pressure, which can lead to inadequate lubrication of engine components. Additionally, issues like worn or damaged bearings, incorrect fuel octane, or a malfunctioning ignition system can contribute to knocking sounds. If the fuel-air mixture is too lean or there are timing issues, these can also result in knocking. It's essential to diagnose the specific cause to prevent potential engine damage.

Do you need a knock sensor on 94 4runner v6 3.0 efi?
Yes, the 1994 Toyota 4Runner with a V6 3.0 EFI engine requires a knock sensor. The knock sensor detects engine vibrations caused by knocking or pre-ignition, allowing the engine control unit to adjust the ignition timing for optimal performance and to prevent engine damage. If the knock sensor fails, it can lead to reduced performance and increased emissions.
