Idle problem

Idle problem
When I start my 2003 WRX it goes to 2.5 thousand RPMS. It stays at 2.5 for about 7 seconds then goes down. After it goes down my check engine light comes on. But if I give it some gas and take it to 3 thousand my check engine light doesn't come on. Has anyone else had this problem? If so how did you fix it? I have tried cleaning the idle air control valve already.

Sounds like your throttle cable is too tight, Adjust it. Clear the code and your idle should be 500-700. Make sure you don't adjust it too loose or you will have a hesitation. Also could be a vacuum leak post throttle body. Done any work to the manifold recently? Lines/gaskets?

Yep thats the code. Like I said check the throttle cables for proper adjustment and binding. Any post t/b vacuum hoses appear to be cracked?
Also worth checking the wire that goes to your power steering pump for a loose/bad connection. If you have a code reader that can see the neutral safety switch turn on a off that's worth a check.
If you tap on the valve with a screw driver the idle change at all?
