Hello. Thank u for taking time read my post.
So whenever I drive my car randomly I get like a quick jerking/stutter sometimes under 40mph at 2k rpm and sometimes during the highway at 60+mph and happens during the hot days, I test it during the night doesnt do it. I change my spark plug and oil change, next week I'm going to do coolant flush and last month I did my timing belt. Only engine code got is p0420 any idea what it is?
