Aright well, sinc ea couple days now my civic b16a turbo is acting weird, when i push the car at high rpm i can hear some kind of silent farts coming from the exhaust sounds like imcomplete burn, but it dint do that before and of course im runing rich when i push it goes down to like 10:something but guess thats normal no ? anyone have any ideas what those silent farts are ?

only does it when i push it hard

thanx for your answer
