My service engine soon light came on, so I went to Autozone and had it scanned and had this error code. PO128 Does anyone know what it means and if it's something that can be repaired easily and NOT go to the dealership? It runs fine just that light is annoying. :mad: My car is an 03 Envoy XL with the I6 engine, it's stock for now.

Thanks
