HELP!!! O2 Sensor issues.....
My '96 with a 5.8 was reading O2 heater codes on all three sensors. With 138k miles I thought it would be worth it to change them out. I did and I'm still getting the codes. Does anyone have any siggestions on where to start next with finding the problem.
I did drive the truck for about 80 miles and I cycled the engine four times since I swapped the sensors. I also cleared the codes about 10 ten times this afternoon.
Thanks.

Check your wiring and the connectors to the O2 sensors, make sure you don't have a broken or burnt wire. Since it's all 3 sensors showing up in the codes, I'm thinking it may be a problem with the circuit supplying power to the sensors.
