96 GC hesitation, rough running...
 

96, 2wd, auto, I-6

had a 171 code (lean), followed by 172 (rich) this means O2 sensors, eh?
do I get new bosch ones, now I get a 138 code, meaning "O2 Sensor Circuit
High Voltage (Bank 1 Sensor 2)
Oxygen sensor input voltage maintained above normal operating range. so, the
cat. sensorvolt. is too high.



the trouble with the vehicle is that it runs rough, and has severe
hesitation. the intke is clean, has new TPS sensor.

here's the rub... this only happens when ambient temp is above 85F. early
mornings, late nights, below 85, runs just fine... what am i missing, and
what about the 138 code?

thanks

One of the causes could be the fuel pump giving up:
