Motor shakes when it first starts up or takes off

exactly the same noise coming from my car i dont know what is it and it doesnt last long after engine warm it gets smooth , can any ody

 

hi
my prius 2009 3rd gen making a same noise and its just started last week when the weather went colder and i dont know what is it , but its only happens for 15/20 seconds when the engine is cold then also only on idle position , then car runs smoothly i have done my complete motor vehicle test yesterday and straight away it went pass no problem at all . .. can anybody help me in this regard ?

 

The best thing to do is to avoid the conditions that make it happen.

So, do not allow a cold engine (ICE) to start and run for ONLY a few seconds and then powered off and allowed to sit for several hours (usually overnight). It's upon the next start up that the noise/rattling occurs.

If yours is doing this in other conditions, you probably have a different issue (spark plugs, coils, fuel, etc).

GOOD LUCK!

 

thanks i ll try not to drive in that noise to switch it off if its make noise then start in a bit . is that ok ? its only happens when engine is cold .
