Welcome to PZ, also there is an Idle adjustment screw that can cause a low idle. When I got my Prelude for some reason it was tightened down all the way and my car idled so low it would stall a lot.

The idle screw is the very last thing you want to mess with. It is set to where it needs to be from the factory. EVERY component contributing to idle including cam timing and vacuum leaks should be inspected before even CONSIDERING touching the idle screw.

Of course, if a previous owner has messed with the idle screw, you very well may need to adjust it, but i highly advise making sure everything else is in working order before doing so.

^^ He is right make sure everything else is good, before messing with that screw.

I did and couldn't find any vacuum leaks even with seafoam, so I checked then adjusted the screw.
