Why does my engine vibrate when idle?
Motor mounts keep your engine attached to the car. Weak or broken mounts can’t hold the engine tight in the engine compartment and creates a vibration at idle. If the shaking subsides when the car is in Neutral, this could indicate the motor mounts are responsible for the vibrations.
What causes diesel engine vibration at idle?
Vibration is easily attributed to misalignment, a bent shaft or a deficiency with a propeller. Often, though, none of these assumptions are true, and the true source of the problem is engine misfire. The combustion process is one of the most important functions of a diesel engine.
How do I stop my diesel engine from vibrating?
The key to improve the noise is to reduce a combustion noise known as “Diesel knock noise”. Conventional approaches to reduce the diesel knock are decreasing combustion excitation force due to pilot/pre fuel injection, adding ribs to engine blocks or improving noise transfer characteristics by using insulation covers.
What does it mean when your car makes a vibrating noise?
Vibration is usually caused by an out of balance or defective tire, a bent wheel or a worn driveline U-joint. You may find that the car shakes the car in an up and down motion. You may feel vibration through the seat, the steering wheel or even in the brake pedal.

Spark Plug Wires– While not every model and engine combination of vehicles today comes with spark plug wires (a lot are now coil on plug), if your Hilux happens to have them, they can go bad and cause a rough idle.
Why is my D4D Hilux motor so noisy?
These motors are famously noisy, especially when cold. This could be a few things, with many reports that the injectors are again the culprit. From our investigations, this is usually the main spindle in the centre of the injector sticking to the bore of the injector.
What kind of engine does a Toyota Hilux have?

Why does my Toyota SA make a knocking noise?
The noise is now so load, it sounds like there’s a hole in the exhaust – severe loud “knocking” sound. And it’s embarrassing – for me and Toyota. The Toyota SA technical representative “analyzed” the problem last week and diagnosed the injectors as “faulty” and needs to be replaced.
