some times a light throttle smoke looks grey.

Scan gauge II would be the cheapest thing to get at this point. And will do much more than just pull codes. It will go a long way in figuering this out. They sell them at autozone
got a scangauge 2 tried it out,but got no codes noticed it runing a little rough ,but starts fine and smokes all the time injector problem ?
need some help to figure it out.
