Have you personally experienced this with the plugs? I had a code 28. Wouldn t run. Replaced the cam sensor. It now runs but the code is still flashing. I did notice a slight spark plug ignition miss. I m going to do the pedal dance & try to clear & see if that takes care of it. What bothers me is that I read in the s manual the the codes are suppose to clear by them selves when running normal.
