I have a 01 QX4
I unplugged the mass airflow sensor when vehicle was idling, s*** it off plugged the sensor in and re started the engine, now I can't get it past 2,500RPM

Is there some method to manually reset the WCU?

Just disconnect the battery for about 30 minutes. Connect it back up and then all should be good to go. Alternatively, buy a scanguage. I got one a couple years ago and it has saved me a ton of money over its life.
