Acceleration, rough idling and startup issue

[Dvor]

Well I started the car up and drove it around my neighborhood some. It seems like the slushy acceleration and rough idling is over, though the engine makes a popping noise as it runs. I'll see if it gets better as it runs or if it gets worse.

Also, can anyone identify this part:



I accidentally broke it off while probing the engine and need to get a replacement.
