Sounds like fuel pump to me.
I've been stressing to them since the day I brought it in that I think it's the fuel pump. That is what most of the threads I read keeps pointing to.
They called me today telling me that it was the fuel pump, and that I will be covered under my extended warranty. I'm starting to think they really tried to screw me by trying to blame my intake.
*Edit- They said my car would most likely be done by tomorrow, which is annoying because my car has been in there since 2/12. My extended warranty only covers 5 days for the rental. They didn't even touch my car until 2/18. Almost exactly 5 days after my rental is no longer covered. At tomorrow 5PM, I will have to pay for 7 days of renting this damn Corolla.
It also angers me everyday, that I come home and I have to stare at my brand new B14s and I can't even install them yet.
