Ok I hooked up my heated O2 wires now I am getting a P1137 ( HO2 sensor low voltage during power enrichment) What is the power enrichment? and a PO137(O2 sensor low voltage bank 1 sensor 2) Now I made sure when I hooked up the two heated wires they were secure! I hooked them up to the rear O2 heated wires. I have the pacesetter header that is why I needed the heated sensor! But now I am not getting the PO133 (Slow response) code! Please help!
