My 03 zx3 started bogging and bucking the day after driving in our first snow storm here in boise. After driving it for a few days like this, out of lack of time to work on it...it got worse yesterday. It went from randomly bogging and bucking at low rpms or on the highway, to barely drivable due to the low rpm bog. The check engine light finally came on but I haven't checked that out as of yet. 147000 miles. Bought it used. Changed the timing belt and passenger motor mount last November. From what I've read on here it could be a number of things from a dirty MAF to the PCV to the fuel filter or fuel pump. Just looking for further insight before I dive into it. Thanks!!
