Ok let me try to explain this as much as possible. While driving usually at low speed, at higher rpms the car does not do this. There is loud metal click, and the car jerks violently, and AF goes lean and It feels like all power is lost. Than the click happens again and AF recovery. I cant get it to do this unless im driving. Its coming from the passenger engine side, and I cannot for the life of me figure out what is going on.

I just rebuilt the engine and it runs and idles good. Ive been fighting with a greedy type rs, which is the only new part I have put on the engine. I cant tell if the click is my BOV slamming shut or what? My boost gauge reads, so I doubt thats my issue. I have done a boost leak.

I cant see why I would be dealing with fuel cut, since I was not dealing with it before, and I am running the exact same setup, minus the new bov (greedy type rs). Only code Ive have is no rear o2 sensor which Ive always had. Im lost on where to go next. I cant get the noise to happen unless im driving and I cant see whats going on.

I read somewhere about motor mounts shorting out but have only found 1 thread about it, and it went no where. But even if that was the case, i don't understand the click. The engine does not move excessively.

And when I mean click, its an audible click like something is turning itself off, on the passenger side under the hood.

Im trying to think of any more important information, so sorry for being all over the place. I will literally take any suggestion to check.

I thought maybe the battery was hitting something but its not touching anything at all. :banghead::banghead::banghead::banghead::banghead::banghead::banghead::banghead::banghead::banghead::banghead::banghead:
 
does yours have fuses on the battery terminal? i had a blown MFI fuse and mine was giving me problems. not to mention all the bare wires in my wiring harness where somebody went edward scissor hands on it
