My CEL came on a few days after I had my exhaust installed. I had it read and came back with two codes. P0131 0-1 Primary Heated Oxygen Sensor Circuit Low Voltage (Sensor 1) and P0132 0-1 Primary Heated Oxygen Sensor Circuit High Voltage (Sensor 1). is it possible to get both? how is it low and high? So im assuming I need a new primary O2 sensor. I looked it up and the OEM one costs around $300. I went to Kragen and they said that they have a universal one for $60 but I think they said I have to splice and match wires. I havent had any huge problems with it on, the only thing is that it stalls once after I turn it on but then its ok the rest of the drive. What should I do?

I keep getting this code also after installing the Meagan Test Pipe, Ive done the anti-fouler fix and it worked for about 500 miles and now Im getting a CEL with the code p0131. Whats up with that and How do I fix it? Also Is the Primary the one in the Header and the 2ndary is the one in the Cat?

Thanks
