I have mctd and been having high bp for over a month i was just told by a e.r doc that he heard a murmur should i see a cardiologist ?

See below: I think it would be reasonable considering the high blood pressure and the murmur but your primary could see you first and do a workup as well and refer to cardiology if it is something he or she cannot manage.

Yes: It will be helpful to do an echocardiogram. Connective disorders can cause cardiac valvular insufficiency or cardiomyopathies or anemia which could lead to murmurs.
