Recently my check engine light came on. A few days later the ABS light came on, then shut off. (the ABS has come on and off a couple of times), then my cruise control light started blinking and quit working, then my A/C yesterday stopped blowing cool air. The light is not coming on for the A/C

I took it in for a diagnostic check
It is saying either "blocked injector", large vacuum leak or MAF sensor fault

My question is: could all these symptoms be related due to a vacuum leak or sensor fault???
