2012 Automatic GT

- the car starts and runs fine for a few moments, then starts to feel rough and eventually the idle rpms drop off and it dies. Earlier today I got halfway thru the boss intake install before I realized I was missing a bit I needed, so I slapped everything back together and was left with this. Possible problems/solutions?
