Well, I noticed three days ago when i started driving my car that it was being rough. The engine seemed to have a different sound to it, and it was riding rough, the whole car was shaking more than usualy (check engine light is on). I finaly got the codes read today, and they came back as the Rev Limiter had been reached at one point, which is nothing, and that there is a misfire in cylinder 3. Well they cleared the codes and ran the car. They pulled the codes again, and the misfires in 3 still came back. Well, I had replaced all the spark plugs the day before, after the problem had started to see if that may fix it, since we needed to change them anyway. When we were changing out cylinder 3, there seemed to be some type of threading problem because it was more difficult to untighten the plug at certain points in its rotation. But it seemed like we were able to get the new plug in fine. Its still running badly and Im wondering what to do....
