ok, so i got 2 new bosch 02's and installed them today. cleared the codes then went for a drive and scanned again. well P0134 went away but P0135 is still there. i got some di-electric grease so ill be checking the drivers side wires and cleaning the connector up some. if theres no broken wires or anything whats the next step?

 

Check and see if there's a fuse for the O2 sensor heater, it may be blown...
