    I recently got a 2016 Mustang V6 and decided to add some mods to it: a Spectre CAI, BBK throttle body (73mm), and Airaid Poweraid TB spacer. Originally the CAI and TB were added, and got error codes right away... air leak from the TB or inlet valves. The rpm's were also abnormally high, around 1300 at idle. I added a spacer, but the problems persisted. I took it to an auto shop but they couldn't do anything other than find that the rpm's would go to normal if the AC was turned on... but when I went to test drive it today it went into limp mode after 6-7 miles; the engine also seems to be bucking a bit, not scary but slightly noticeable.

    I'm going to take it to an automotive shop, but I'd like to get any input as to what the problem might be and what the solution might be.

    Thanks in advance,

    Tom

    Post the codes.
    Sounds like a vacuum leak.

    The initial code and one that keeps popping up is P2282, which corresponds with your reply... a vacuum leak. My thinking is that the leak should be easy to find and fix, right? Thanks for the reply.

    Maybe you forgot to put a vacuum hose back on?
    And a tune might fix the Air to Fuel ratio.

    Check the hose on the throttle body.
    It goes to the evap system, it has a tendency to rot.
    Check all the hoses the easy way, get a cigar, take any one of the vacuum lines loose, and blow smoke into it.
    Smoke will come out where there is a leak.
    Here is a link to a video by crazy Scotty Kilmer, showing how it is done...
