Ses Codes!!!

i've been on here before asking about my ses codes. I have 0137 and 0157. Well i used this program called auto enginuity and the codes are b1s2 circuit low voltage and b2s2 circuit low voltage. I replaced the 02 sensors with new bosch sensors and the codes came right back. The program has 2 parts to every 02 sensor: Sensor output voltage and sensor fuel trim. For both b1s2 and b2s2 the sensor output voltage is fine and the sensor fuel trim comes back in red meaning a problem. The program shows % range for the tests and the sensor fuel trim is at 99%.

The program also lets you read the codes and look at some data from your car. There were few fields that were highlighted that i think could be problems: EVAP excess vaccuum test 1, EVAP excess vaccuum fail test 1, MAF above expected value during no EGR idleoff test, EGR deceleration test. Can these things be related to the codes?

I doubt many of you have this program but any ideas are appreciated.

Oh and the car is stock except FRA, K&N, and SLP lid

Just to be sure...you replaced both rear (postcat) 02 sensors and you have stock cats? Don't think the EVAP/EGR stuff has anything to do with it - could be wrong though. Look up the codes at www.gearchatter.com should find the answer there.

yeah i replaced both rear sensors and i have stock cats
