P0140 points to the rear O2 sensor and P0134 says front O2 sensor. Pretty unusual to have bot of the sensors go out at the same time. Did you clear the codes and see which ones came back first?

Did you run over a tall speed bump and scrape the O2 wires for the rear sensor? You also might just try cleaning the plug area on to of the tranny housing.

You are right about it is probably time to replace them, they do not age well. If you do, try to get OEM as they will normally work better than 'others'.
