HOw is your filter condition? Ck AFM and look for a leak and you might want to ck your compression.

i had the same proble look by wear the moter and intake meet and you will see a black nipple cover take it off and there is a stander screw try twisting it one half turn to the left if dosent keep plying with it telll it works left or right

But, first you need to ck for all other possibles before you mess with your fuel/air mix and idle.
