Hey team S197. I have been out of the scenery for a long time since I sold my 2011 5.0, but just yesterday I bought an used 2013 GT500 and today I am having some issues I am not familiar with. Long story short, the car feels like a normal 5.0 as far as power level but it might be me and the long time I don't drive a mustang. if I am cruising in fifth gear around 70mph and push the gas pedal to the floor the gar slowly climbs up and studently rpms shoot up. That makes me think maybe the belt and tensioner are slipping or something. The real issue is that after the car is warm or hot, I turn it off to go anywhere for 5-10 minutes and when I try to start the car it is super rough and sometimes it turns off, like limp mode. IF the car stays on very rough, I cant accelerate at all because is like in limp mode. I have to turn it off and restart it then is good to go like nothing happened. Today it did it just like that but additionally the wrench light came on and after I turn it off and on it disappeared. No DCT codes stored or found when I checked with the OBD2 in AutoZone. Anybody have a suggestions before I take it to the Ford dealership and they rape me for basic diagnostics? I have never worked on supercharged cars or GT500s yet.
