    have a 91 b18a teg engine in a 90 lx. Keeps throwing a code 43, everything runs fine, and drives fine. Car throws a code 43 after about 2 mins of driving. Was looking at a helms manual and says something about replacing a HO2S sensor??? is it the same as O2 sensor? code Do civics have this if so, where is it located? I don't think it's my fuel system because everything starts and drives fine, not sluggish at all. Any suggestions would be appreciated.
