under part throttle like when accelerating around town there is a popping sound in the exhaust and you can sometimes feel it in the engine, its coming from the engine, like a miss sort of. its been doing it for a while, even before i had my SC on. its not loud but i can hear it easily. you cant really hear it if you give it some gas, just when its cruising and when accelerating slowly in town
i duno if its rich or not enough spark?
