Ok, 1996 sho, first broke cable for intake valves ( or what ever their called) got a cable at pick n pull. Now car started idling rough and sputters when accelerating (bad) have to baby it to even move. An sometimes takes off fine, idle is always rough. Highway is ok but can feel hesitation when lift on pedal...codes: 0300,0302.....and I don't understand this one p1121...?
