I was getting code 45, Check engine light, Also it was lacking power. Turns out it was a mouse nest in my airbox! Cleaned it out, now it runs like a dream, + no more check engine light. Just wanted to put this out there incase anyone else was having the same issue and save someone from doing a plenum pull for nothing.
