power issue

Pull your EFI fuse, 15A in engine compartment fuse box. Leave the fuse out for a couple of minutes. This will clear loged codes, turning off the ignition will NOT clear codes.
Start the engine and go for a short drive. The ECU will go through a "learing process" for a short period of time.
Return home and check for codes again.
This will give you which code(s) are active and not loged. If you have codes, let the them run through two or three times to make sure you counted correctly.
Fuel cut @ 2400RPM, I doubt it.
Vacuum/boost leak is a posibility. However, if you have an active 51 code, most likely it is an issue with the throttle position sensor or wiring.
