The car runs great and does not shows any smoke of any color, BUT, after driving for 15 or 20 minutes
seats all over the car a black dust, really black.

I took it to the dealer and they replaced the fuel pressure regulator, it had a leak. smell and black dust seems to go away.

I week later again the same black dust all over.

Back to the dealer, now they said car idle to fast need to replace the speed control unit. I DO

Few days later.. you guessed it blk dust everywhere.

I took a wild guess and changed the injectors, same story.

Hints: I the car leaks power steering fluid and a bit of engine oil. Can these oils seat on the exhaust system and be the problem?

Original exhaust system replaced by after market one, and I believe that is when the problem started.

Any advise will be greatly appreciated.
