So after running the engine a little bit today, it doesn't seem to be running properly, some insight from the peanut gallery of experts would be greatly appriciated. The problem i have is two things that may be related. The first problem is illustrated in the image, is a vacuum hose missing from this?:

Second problem, When i accelerate the engine pulses a bit, and it doesn't seem to run in its full potential, also sometimes when i accelerate it accels, but when i get to a certain part of the pedal pushing it studders until i release the pedal a little and it works better. Please help with this...
