My corolla did something similar to this one time and it ended up being a bad ground. So check those

Anyway no rev over 2500 usually means a problem with the MAF or the MAF wiring. Pull the codes off the ECU and see if that helps you out any. It's possible the MAF wiring itself has a short in it...
Also check the obvious stuff, like boost/vac leaks

Usually MAF wiring like mello said.
