Ok so I decided to take my car to the parts store to try and get it scanned even though there was no CEL on. And it did show 2 codes P0110 IAT Circuit malfunction and also Throttle pedal position sensor. So im assuming previous owner disabled the cel or it burned out or something. At the parts store he said it was flashing converter and o2 sensor but no codes for it so he said those may be showing because the other 2 might be affecting the converter and o2 sensor. So anyone have experience with these problems?? Help is greatly appreciated, just got the car and really want to enjoy it soon. Thanks in advance!!
