My motor is not running quite right. Seems to be lacking power at times. Sometimes it feels like it has absolutly nop power until the turbo spools up and then it is fine, and other times is seems to have a normal amount of low end power. The motor is basically stock(fmic and header) I have changed the O2 sensor and I need to put in new plugs but does it sound like there is a bad sensor somewhere or something else completely different.

Thanks in advance for any help,
