P0132/P0138 Diagnosis

I have catless longtube headers on my car with no tune. This means that I have a CEL. Well since I need to pass inspection soon I decided to install o2 antifoulers (basically raise the sensor out of the exhaust stream). After installing them I cleared the codes and then within a few miles I got the code P0132 for having too high of voltage on the front sensor drivers side. I went ahead and switched the left and right side front sensors and cleared the code again. This time I got P0138. There's definitely something wrong with the sensor/wiring on the sensor. I have ran the codes before and I didn't always have the code but it is possible I developed it somewhere along the line or I messed the sensor up during the antifouler install. Car only has 14000 miles. Also the sensors were extended by splicing longer wires in since I didn't have extensions when installing. The wiring looks fine, however. What do you guys think I should do?
