Have this code for bank #2. Car is 2002, 150K, owned since new, well maintained. Internet search comes up with this suggestion: unscrew the oxygen sensor and screw in a sparkplug non-fouler into the cat; then screw oxygen sensor back in.
1. Has anyone tried this with any success?
2. Will this cause any issues for timing or fuel injection? I will try this but the non-fouler must first be drilled out so the oxy sensor can fit. I need to order proper size drill bit first.
3. What is the cause for this code?
4. What is proper fix?
