Have you checked your intake system? I also experienced this in my advie, since we're having pretty much the same engine, likely it might also apply to you. The air filter was found to be so screwed up it's so dirty the air filter was damaged, it's been replaced, tapos tappets were also adjusted, no oil-change involved. Yun nga lang pala manual tranny yung advie ko.
