I replaced a few more things and they didn't do jack **** to help with the code plague.I replaced the spark plugs a couple weeks ago and the thermostat about 1-1/2 months ago and and code 28 from chart 7 "catalytic efficiency" code is still making my CEL light up. Does anyone have any other suggestions? I am getting really annoyed with this situation and would like to resolve sooner than later. |
