My car is throwing codes 13 and 32. I was wondering what some possibilities could be that would cause it to throw those two codes. The O2 sensor is fairly new and all of my egr stuff has been gone for 3 years and I have never had it signal the code. I have a 160 thermostat and I read somewhere that the motor could be running too cool since I havent had my chip reprogrammed, and that could be tripping the code. Any help is appreciated.
