Engine does not Revv , does not go into drive or reverse

What is your question?

Suddenly my engine does not Revv, like I can push down on the gas completely and nothing happens, all the time , this happens in idle, reverse, drive any shift I have it in and it just does nothing. . I have checked mass airflow sensor and transmission fluid I don’t know what else I should be checking for. There is no noises , car starts perfectly , is it just goes nowhere

How long has your 2009 Nissan Cube had this problem?

Started a few weeks ago and I would just have to turn it on and off and it would be fine
