Pick up became very DULL as engine got hot plus knocking also appears,
The reasons are follows:
- Contaminated fuel.
- Knock sensor poor performance.
- Check exhaust system. If clogged, remove or replace the honey comb porcelain.
- Check ignition timing with scan tool at idle speed. (5 - 8 degrees BTDC).
- Check engine oil level. If the oil level is low, it may be one of the reasons for knocking, because oil may be burning during the combustion.
- Check fuel pump pressure. ( 41 - 49 psi).
- Remove negative battery terminal for 5 Sec or more. Reconnect the terminal. Close all doors, remove all electrical loads like room light, parking lights, blower motor etc. Start the engine and hold the throttle at 3000 rpm till the radiator fan becomes on to complete the idle speed relearn process. Release accelerator pedal after the radiator fan becomes on, and let it idle for 7 min more.
- Switch off the engine for 3 sec and you can then start and drive the car comfortably.
Hope that works.

Hello
Yes, vitz 2006 got idle engine stopping system.
I got the same model and was told by my mechanic that these car have that system installed.
Also you can notice yourself that when you are reducing the speed while turning or stopping, you can feel the engine going to die. i mean idling it self.
I h ope you get my point as its hard for me to explain

Knocking can be caused by a bad bearing somewhere in the engine. When the engine is accelerated it might go away due to higher oil pressure.
When did you have the oil changed and how many miles does it have?
Is the knocking rapid (5 or 6 times a second) or periodic (1 or 2 times a second)?
Some knocking is due to low octane gasoline if you experience it at highway speed.
Good luck on solving this knocking problem.

not sure exactly what you mean but iam assuming you mean the ABS light comes on then the vehicle stops ?' if this is the case clean the sensors on each wheel as they could be dirty with a lot of metal dust sticking to the sensors ,which is throwing the light on which is causing the computer to detect a fault and shut the car down
