Cold Start Rough Idle

Feels like a complete miss every once in awhile, it has no real rhythm but I can definitely feel a miss in the exhaust pipe pressure, I have not checked the cold start injector. Any idea on the average life of this part? I pretty much have been slowling replacing everything in an effort to do a complete restore when it hit 100k miles last month.

Also another thing that I did read about is the HAC sensor, anyone know if that component failed would it cause my issues?
