I noticed my 2012 SHO felt slower on the acceleration. I did a 0-60 test and I got a 7.4 second. I usually get 5.5 seconds to 60. So I scanned my car and it showed the code P0020 'A' Camshaft Position Actuator Control Circuit/Open Bank 2. Does anyone know a solution or how to fix this? It would really mean a lot your your guy’s help!
