I have an 87 Nissan Sentra with a carbonator, the oxygen sensor light, charging sensor light, brake light and taillight replacement light came when slowing down to a stop, they stayed on at several red lights after driving highway speeds( 45ish-50). Once I started moving again they shut off. After that day they have not came back on. I have been unable to find anything loose, broken, or missing. Is this something I need to worry about? Does anyone have idea what might have caused that? Thanks!
