I have had the ecu scanned several times and the only thing that ever showed up was for the o2 sensor, which is back in now. I had it inspected a week ago and the o2 sensor is fine now. If i am the problem thats fine, but I'm not really sure what it is I'm doing wrong.
Not sure where the confusion with the tuning happened, but it has a stock tune.
I was thinking about putting the parts back on, because i never noticed it before. But its very loud, and if it gets worse i want to be able to hear it.
