Well after driving 30 miles the CEL came back on. I'm going to add another spacer and see if that does anything. Otherwise I guess I'll try an L spacer before buying a cat.

Ok well I'm at a loss. After installing four spacers I thought I had it fixed but 76 miles later the cel came back on so idk what to do. Should I try three or the L spacer? I'm about ready to just get a catted test pipe but I'll probably need a spacer for that too?

Well the spacers arnt working. I've tried a variation of spacers and all end in the same result, CEL P-0139, Oxygen Sensor Circuit Slow Response Bank 1 Sensor 2.

Ive tried 2 spark plug defoulers, 4 spark plug defoulers, and an L shaped CEL defouler. I get the same dang thing every time.

could the o2 sensor be bad or is it simply my spacers don't work?
