    The connection between the Intake and the TIP was not flush with the stop, but still on securely. I pulled it apart and re-tru'ed it against the stop and tightened it down. It's been three days since the reset and CEL is still off.

    Here is to hoping.

    Asking a quick question regarding your post.

    Once I fixed the problem it instantly went away.
    Hi, I wanted to know what you changed because my LTFT is at 20.3% as well? I cant seem to get rid off P2177 and my freeze frame showed LTFTs 20.3%. Can you please help.
