Had some problems with the bank 2 sensor a week ago. changed with a Bosch replacment. she has 59,000 miles on the clock. is it common to replace all the 02 sensors when one is shot?(a new one having better readings than stock) last week i got all sorts of codes with led me to believe the sensor was shot. now i only got one code p0133- Heated up stream 02 sensor circut low responce<<bank no. 1>>. is this particular sensor the one on lower portion of the exhaust manifold? (98 SE 5 spd. 59,000k)-Thanks
