Car has been rather suspicious at times, low rpm idling fluctuating greatly and sometimes dying off when shifting into 'D'. The problem arises when I start-stop my car a few times withing a short period of time (i.e. carpark to 7'11 to grocery store to carpark within an hour or so)Went to Tamilselvam (bawah pokok PJ), and he just removed my Idling sensor and gave it a good wash, since he said it was clogged up. Didn't charge me for it, and the problem has gone away.
