my vitz was running fine earlier but recently after I have cleaned its PCV valve, it has started vibration when it is put in D or R and brake is pressed, after brake is released n car get in motion the vibration disappears, also if the car is put in N or P the vibration disappears. Vibration was not there before the adventure of PCV cleaning which was suggested by experts on PW .
Lesson learnt never fiddle with anything unless it is giving problem.
solution is solicited please.
