If you car was working before and you never touched the idle screw then that is not your problem. Sure it may temporarily fix your problem but it's a band aid solution. I would look into it more and actually fix whats wrong.
I myself am going to clean out the IACV and the TB. As well as my air filter and fix any boost leaks I may have. After all of this I may adjust the screw but I'm betting I won't have to.
