"Why does my car run wrong?" *proceeds to not attach logs* <-- 90% of people on here.

Please don't be one of those people.

Jesus Christ, lol. WATISHAPPUNINGUYS. Seriously, post a log. If you're running lean, then you need to adjust your fuel... If you don't feel comfortable adjusting your tune, pay for a tuner to do it.
