Thank you very much for your detailed reply.

 

I will use a fuel additive, and update in this forum.
Thanks.

 

Hi! Are there any updates from your side? I have the same issue

 

Yes, Note that i didn't have the chance to use fuel additive. I tried to move to better Octan fuel which didn't fix this issue. But...
I went to Mazda garage, they have cleaned the throttle, cleaned all the soot in the fuel system, and replaced the spark plugs.
and "THE ISSUE IS SOLVED".

 

The injector/fuel cleaner additives are designed to keep these items from getting clogged.
They will not help if they are already clogged to the point they need cleaning.
I would recommend using the cleaners now that your repair has been completed.
At a minimum they will at least extend the need for a future cleaning.

 

Definitely agree that they're worth using. Preventative maintenance never hurts .
