What is your question?
8 codes. 2 old ( both knock sensors, both have been replaced along with the wiring harness). Yesterday car started to smell faintly of gas fumes. Today car was running fine , then at stoplight it started to idle rough and stumble. And 6 new codes along with it. P0120, P0441 (shows this code twice), P0300, P0304 and P0305
After the hands-on diagnostic testing has been completed - a beneficial explanation can be given. Good luck!
