I own a 1996 Subaru Legacy Outback, 2.5L, automatic that is giving me problems. I connected an OBDII scanner and it showed 1) P0130 O2 circuit malfunction 2) P0400 EGR flow malfunction and 3) P0740 TCC Circuit malfunction. After writing down the codes I erased the codes and the check engine light went out. Also, the car drove like it should the entire 14 mile commute to work. At that point the check engine light came on again. When I connected the scanner again it displayed the same O2 circuit code, but no other codes. In as much as the codes reflect a problem with the circuit I am wondering if there might be a problem with the computer module. Any suggestions?
