Diagnostic Codes Help Please
My 02 Mustang GT has been acting up lately. The idle RPM has been sticking around 2K and accelerating itself to about 20mph without me pressing the gas pedal. I replaced the TPS figuring it would fix the sticking of idle, but it didn't do anything. After running a diagnostic on it, it pulled quite a few codes. Here they are listed: Malfunctioning control speed, idle speed auxiliary inputs. And 4 errors relating to malfunctioning of air fuel. The air fuel problem has been going on for awhile and I believe it's the piece that attaches to the stock intake itself. My question is the RPM issue and why it wants to accelerate by itself. The car is automatic if that helps at all. Thanks for your help!

your throttle body is probably dirty, you need to check throttle plate, these are real bad about carbon build up especially if you have an oiled air filter. over oiling these filters causes dirt to build up in throttle body. don't clean it while it is running!
