Catalyst System in Lexus ES300 / Lexus ES330 / Lexus ES350 / Toyota Windom Club Posted July 16, 2014 My car kicks when I step on the throttle and sometimes when I let go. When I step on it real slow it actually works fine and accelerates smoothly. Shifts into gears perfectly fine other than that it kinda jerks a bit at first. Took it to auto zone and did a diagnostics test and came up as a catalyst threshold. I was wondering what could be causing this?
