about a week ago i misshifted my car and bent some valves in the head... i did a compression test and all were 230 except number 2 which had 15.. anyway im gettin cel 72,73,74 which is cylinder number 2,3,4 missfire. the car runs still a lil shaky at idle and a lil loss of power. but what could be causing the cel for # 3and 4??
