The vvti solenoid comes on about 3000 rpm and a failed solenoid can cause the engine to burn oil as well as the loss of power above 3k.
I'd start there, maybe take it off and give it a clean and check for movement

Clean throttle body and ISC valve.

Additionally, new spark plugs, new air filter and MAF sensor cleanup will do no harm.

And as it burns a bit of oil, take it for a very good spin just before a retest.
