My car makes a ticking noise when I am driving. It goes away for example when I am on the freeway and I want to keep the car at 65 MPH. Only when I am trying to keep the car at a constant speed does the noise go away or when I am not accelerating. It seems to come from the drivers side. What is the cause of this and how can I fix it. Checked my oil level and its good (just got done doing an oil change). Thanks in advance.
