You know, it's really damn hard to help when I have to read 15 back threads about the same thing. All of which have very little information to go on.
Nearest I can tell from all of them combined, you opened the hood. I can't find any procedures you've gone through to test parts, other than the obvious scanning for codes.
So please take more than 30 seconds to make a post, make a post, make a post, make a post and explain what you have done in detail so far.
Also, I find it coincidental that you didn't have problems until this Spectre intake was used. And no clue if you're still using it.
BTW, edit your thread and don't bypass the swear filter again. 1 and only warning I'm going to give.
