What is the proper air conditioning refrigerant pressure for a 2004 Scion xB? Should the pressure reading be made at a specific RPM? My A/C has been slowly loosing cooling over the last couple of years, now it really only cools well when traveling above 35~ mph, not so well at all in stop-and-go situations. Does it sound like I am on the right track to recharge the system? Works pretty well at steady-state speeds...

I have a 1999 Toyota Avalon. I noticed the small plastic grille below my left headlight missing and there's a dangling plug inside. I can't figure out what used to be in there. The car still runs fine. Inside the passenger-side grille is a grey plastic box, probably connected to a similar plug.

My 2006 Audi A4 is having ignition coil problems. And the dealer is saying because it's water damage related, it's not covered under warranty. I have NOT had the engine cleaned. I have NOT driven into a lake and I live in California where rain is minimal. Help me to not be screwed. [more inside]

My hatchback car (Honda Fit) doesn't have a separately-locking trunk or glovebox. Can I add a lock-box or secret compartment somewhere inside the car for stashing a few items, for those times I must turn over my keys (parking garage, valet)? Ideally I'd only be securing/concealing 3 deck-of-cards-sized items: iPod, GPS, EZPass. There are no official Honda accessories that do this, nor can I find any Fit-fanatic mods that have addressed it.
