smoke at reving is probably piston rings, and idling parts it either ur vaccum is plug in wrong or missin a vaccum line somewhere or ur map or throttle positions sensor is bad

I had the same problem, but mine were the injectors. The small seals were bad n gas was leaking into the engine? n through exhaust pipes. Smoked upped the whole block. Got the injectors done and so far so good.
