Correct, your PCV valve is missing

it must have been that way since i bought the car what kind of problems does this cause.

the end of the black hose should have the pcv valve on it, the pcv valve goes into the black grommet
without that, if the rest of the pcv vacuum lines are hooked up you would have a massive vacuum leak from the pcv system causing a high idle and generally shitty performance.
