Subject: Vacuum modulator and color of smoke
It was grey and maybe blue. My mechanic said it was oil burning. He said the Vacuum modulator when it goes bad burns oil. It's a trans part. My question when he cleaned the fuel injection system could he have done something wrong and created the problem? When I first drove the car it seemed to lose a little something when I got it home after driving 50 to 60 miles then back down to a stop and going again it seemed to want to stall right around 20 but would pick up. The next morning is when the smoke happened. It's not a steady stream of smoke just happened 4 or 5 times before I got it back to him. I probably drove the car 20 miles at least before returning to his shop. Could there be damage to a piston or a valve due to a fuel mixture problem with the fuel injection system after he cleaned it.
I don't think the injection cleaning will caused the smoke
If the vacuum modulator is leaking transmission fluid will be drawned into the intake and get burn in the combustion chamber and as a result it will produce a whitish looking color.
Bluish color is an indication of oil being burned-get the engine compresssion checked to identify a problem with valves and rings
