Weird popping noise and p2254 code

[Results23]

Hey guys i have a 2016 mustang GT that I have been having a lot of issues with over the past couple of months regarding misfires and bad 02 sensors/wiring. I have fbo mods air intake, intake manifold, corsa exhaust, headers and 47 lb injectors. I fixed the misfires but I’m hearing a popping noise coming from my throttle body of my intake anyone have any ideas ?

That almost sounds like an intake leak to me. Have you lost any power? Does the sounds change when you hit the gas?

Also, snug your injectors and plugs as well...

I do a little bit I replaced the intake manifold last Thursday, are you saying an air intake or a intake manifold?

This is an older video, of the sound I’ve replaced spark plugs, coil packs, intake manifold and the fuel injectors so it’s looks little bit different now.
