What went wrong?
Recently I've replaced a fried ECU, and was diagnosed with dead O2 sensor. I have 2 others..... both of them keep the checck engine light on. Perhaps the wiring connecctors TO (from the wiring harnesses) the O2 sensor connectors have gone bad?
Or maybe the O2 isn't grounded properly and caused my ECU to fry earlier.
? Any suggestions?

Bump:
i checked the ground connection near the cat conv...... seems to be fine.
Anyone have ideas on the wiring setup for the front O2 sensor? ......... is the middle one a ground? or does the O2 ground through the engine....?
