So this just started yesterday on my way home while I was in traffic. While I was slowing down with foot off the gas pedal my car started to like jerk or buck. It seems to happen only when foots off the gas pedal. Driving it’s no problem. I checked for any vacuum leaks but there isn’t none. I maintain my vehicle very well as far as oil changes tire rotations, keep coolant levels topped off. I have also just recently changed o2 sensors. Anyone have any idea what it could be?
