01. When slowing down the car and pick up again there is a jerk or lose of power suddenly (I rev the accelerator roll slowly and then suddenly the power kick in at a fast speed. 02. Every time stop at traffic or any stop the vibrate and like engine going to die off (error code P0154) I've change 2 Oxygen sensor still the same)
03. Where can I buy Air Filter Box top cover (my top cover crack) and where to buy stainless steel drop in filter.
