mate... i need your help.... i got my car tuned at stafford and cleaned the injectors+ throtlle body and changed the fuel and air filters. the pick up is far better than before but i have a small concern.
even before i did the tune up, when the car is stopped in traffic while in D mode, RPM tends to fluctuate and reaches even 200 sometimes but it becomes steady when i shift to P mode.things are still the same even after the tune up and i want to know whether this is normal or do i have to rectify this??
this hapens only some times and specially when i press the breaks and stop while driving at moderate speeds.
