Why is my Isuzu 20LE Engine knocking?
Engine knocking in your Isuzu can occur due to several reasons: * Using spark plugs with an inadequate heat range, which can be solved by installing spark plugs of the correct heat range. * Using fuel with too low of an octane rating, which can be solved by replacing the fuel. * Incorrect gear selection, in which case you should caution the operator to select the correct gear.
What to do if there is trouble in the fuel injection system of Isuzu 20LE Engine?
If you're experiencing issues with your Isuzu's fuel injection system, several factors could be the cause. The fuel pressure control valve, fuel filter, fuel pump, fuel tank, fuel pipe, or fuel injector might be clogged or defective, requiring cleaning or replacement. The fuel pump relay could also be defective and need replacement. Additionally, check for loose or defective power supply cables for the fuel pump, and ensure the Manifold Absolute Pressure Sensor, Engine Coolant Temperature (ECT) Sensor, and Throttle Position Sensor circuits and sensors are properly connected, adjusted, and functioning.
