i recently returned my turbo s2k back to stock and now every time i engage vtec the engine light goes on and the car wont rev past 3000rpm i know it has something to do with the camshaft sensor, but i recently replaced the faulty one... any ideas?

 

I would also check the vtec pressure sensor on the vtec soloniod (the one that hangs out horizontally. Also, check the knock sensor and connections.
