RPM fluctuating from 400 to 600 lights are dimming and brightening while in park. I have replaced throttle body I was wondering if you guys could help me identify the idle air control sensor mass airflow sensor is good. Thanks

Lights dimming and fluctuating in park?

I would definitely load test/check your battery and alternator first.
