Any cels? And was the smoke blue? I bought my 02 and stuttered under boost and one day had a huge puff of black smoke behind me and started getting a misfire cylinder 4 code shortly after. Turned out to be a coil pack. But you should compression test regardless. Get a cheapo tester at autozone. Just be sure to tighten the adapter on the end of it before you use it. Don't want to loose that in a spark plug hole! Good luck bud.
