GS300 SE MKII 1998, UK Spec.
Just after Engine steam Clean: huge vibrations at Idle, Rev Counter jumps up and down between 400 – 800 rpm, low performance, and more fuel consumption. Vibration causes whole car to vibrate.
It was fine before Engine steam Clean.
I think I need to clean, throttle body or Oxygen Sensor or Air flow Sensor?
What shall I do? Please help.
Regards
