That full tune up. Do it.

Replace the gasket for the VTEC solenoid.
Get on Google and put all your question in a search query and I'm betting you get all the answers to your questions.

I don't do "what ifs". Fix what you know is broken/needs fixing.

P0505 : "Idle Air System Malfunction"

Generally points to a Dirty IACV, or a major vacuum leak. First try looking for any disconnected vacuum hoses. If you do not find any, inspect the hoses for any leaks.

If these two fail, i'd suggest cleaning your IACV as its probably never been done.
