This is a very rare problem that happens a couple time a year for me.
It has only happened after shutting off the car and letting it sit for up to an hour before starting it up again.
Essentially, the engine revs to 2000+ and when I press the throttle, it'll rev higher and maintain that RPM and not come down. The last time it happened (a couple days ago), RPMs kept rising to about 4000 before I turned it off. The only way it gets better is for me to initiate a stall or for it to stall out on its own.
Possible issues:
It's such a sporadic thing, which makes me think it's not a dirty MAF or throttle body.
Anyway, if any of you have had this happen, or know what it might be, please chime in. I feel like if I start replacing stuff, I'll just be chasing ghosts and waiting months to see if it happens again.
Thanks.

Possible issues:
- I have an e-Force supercharger with an SCT 3 tune.
- I also had an issue with the smart junction box getting wet which caused my daytime running lights to activate.
- Throttle position sensor?
- Anything else?
