Subaru Stars 2008 WRX overheating problem??

I have a 2008 Subaru Impreza WRX and it recently had multiple problems. I would start it up and drive it for a little bit and its fine. But after a little while of driving, the RPM's go way too high. (Above 1500 RPM) second gear becomes extremely jittery and the turbo doesn't seem to work. The longer I drive it, the higher the RPM's go. (above 3000 rpm)

I went to autozone to see what error codes i have and they were with my MAF censor and my crankshaft sensor. But i tested them and they both seem to work but i still don't know that the problem could be.

Does anyone know what could be the problem?? I would really appreciate it, thank you.

What do you mean by the rpms go higher? High idle? Your description of the problem doesn't make much sense.

Yes. the hotter the engine gets, the higher it idles. and it runs rough. But usually when im at a stop light and i start driving, everything works fine for a little bit, but then it starts running rough and idling high again.

Check vacuum hoses first -- TGV gaskets on the 08 tend to leak after a time too. Thats a little more involved.

so we just checked the vacuum hose lines by blowing air into the intake, and we found 2 cracked vacuum hoses. Thanks for your help! about to go buy them and see how the car runs!
