My 03 GS300 makes some annoying noise when I stop at the traffic light. There're some exceptions though...1)if the A/C is on, the annoying go away because the idle maintains little higher (500 rpm); 2)drive at night with the highlights on that also raise the idle higher around 500 rpm
At normal driving condition, A/C and headlights off, if I stop at the traffic light or sit in the bumper to bumper traffice, I can hear the ABS resetting noise and the annoying noise due to the low idle with gear at D. More interesting is that, if I change my gear to N idle move up to 700-800rpm and all the noise go away.
I'll be really appreciated if someone can post some notes here to figure out the mystery! Thanks!
