    Sounds like there’s a leak somewhere.
    Could be the massive horses just rearing to run though.

    I don’t know it wasn’t doing it yesterday but today it’s pretty bad possibly a dirty MAF sensor?

    Double check for any air leaks. Also, were you careful re/re MAF? They are pretty fragile.

    Modern vehicles, no.

    K&N intake system actually improved performance in my 2007 ranger, believe it or not. It was fantastic.

    Then I welded in magnaflow muffler and started getting about 25 miles more per tank.:notsure:

    Take it off. Did it fix it? Yes? Leave it off. No? Continue troubleshooting.

    If you have access to obd2 monitoring apps. MAF at the hot idle (no load) should be 2.6-3.7 g/s.
