Recently my car has been having an issue where it will idle high, between 500 and 600 rpms higher than what it should be. Once it idles high, when I give it gas, it sputters and stalls. Upon restart, the exhaust is pitch black, and smells like pure gasoline.

Originally, the engine code I pulled was for a bad TPS. So I replaced the TPS, and I'm still having the same problem, and now I've got another code being thrown, for an 'RPM Signal Problem,' a code 17. What does that mean, and how can I fix it?

 

there is no spoon.

I mean, there is no code 17----check these.
