Multiple CEL help

[stang305]

Need help I’m 2015 mustang gt with 10k miles procharged with everything else stock engine wise.

I received these codes while WOT

Ive been boosted for 5k miles no issues

P0300 (random/multiple cylinder misfire detected)

p0301 cylinder 1 misfire

p0306 cylinder 6 misfire

p115e (throttle actuator control throttle body air flow trim at max limit)

have you had this before ?

did my stock intake manifold take a crap?

Any info I would appreciate thank you

That's not uncommon even on non supercharged vehicles, your throttle body is most likely on the way out. I see it all the time at work.

That brings up a question (in my mind at least). I wonder how well our plastic intake manifolds deal with boost pressure? Obviously on a roots type it doesn't come into play.
