    You have to disconnect battery before doing all that

      I can understand why you would say that. I just saw the video again and on 1:58 of this video more codes came on. But the system also cleared them away. Would that be the affect?
      What is your opinion about disconnecting the battery before cleaning? Why would you recommend doing this first?
      It's good to hear other peoples opinion of what they know. I am not a mechanic but I like researching car things.

    My Longft2 stays around 43-48%. What could the issue be? Maf?

      When both bank 1 and bank 2 short-term fuel trim numbers are negative numbers at idle, and they get better when you accelerate, that indicates bad MAF sensor. You can also inspect the MAF sensor visually take it off and if you do not see a small electrical sensor wire going across the inside of the MAF sensor then it is bad. I noticed that when I bought a new one. The new one had an electrical sensor wire going across it. Both short-term and long-term fuel trims have to be close to zero and no more than -10 or +10.

    So likely just the MAF was the issue

      @@danlarson8731 Its duralast mass air flow sensor from Autozone. It was about $100. Denso is better brand it cost alittle more. But I just went with the one in the middle price range. There was another cheaper brand for like $30 less.
