the only thing is that it seems to run a little better when its cold outside. when it makes the coughing sound its coming from somewhere around the turbo. ive checked the live data on my ap and my afr stays the same even through the rough spot. if i floor it it gets through the rough spot easier. it makes it really hard to drive on the highwway because i have to either stay below 2700-3000 rpm or above or else it gets really rough. its getting very frustrating. i want to get my car out and drive it but it frustrates me that my car doesnt run as smooth as it should.
