Default s4 barely idles if it doesnt stall. Epc light on. Wont let me use the throttle.

I'm having some trouble so i was seeing if you guys could offer me any advice/possible solutions.

So my car was running fine. I tried doing piggies. I started to punch the precat but only did like an inch section. I put it back together, and it wouldnt run right.
  • It just stalled when i tried pressing the throttle.(only SOMETIMES the epc light was on)
  • I unplugged the egt sensor and it ran, but only for a couple miles, the epc light came on and all it would do is idle. (Pressing the throttle did nothing at all.)
  • Even after resetting the battery, it was still in epc mode and just continued stalling or having no response to throttle.
  • So i took the pipe out because i figured it was clogged causing the egt sensor to shut it down.
  • With the pipe removed, it still does the same thing (idles/stalls. EPC light on. Throttle does nothing)

I cannot bring it to the shop til tuesday. Do you guys have any idea what could be going on? ANY HELP WOULD BE GREAT and i'll greatly appreciate it. Thanks.
