There is an idle air control valve, yes. I do suppose that a malfunctioning IAC valve could cause the engine to fail to idle sometimes. I don't know a good way to test it, though.
At WOT it still definitely relies on the MAF sensor. It does not rely so much on the oxygen sensor though.
The oxygen sensor connector is really annoying to disconnect. You kind of have to push the clip away from the body of the connector while pulling on it, and it's likely somewhat frozen in place. It took me like half an hour to get it loose the first time I tried.

Here's a weird one for the gas smell...
Check the gas cap. Heard it leaking air after a drive. Thought I got a flat until I realized where it was coming from. That was the source of my gas smell although it didn't cause any drive issues.

Well I notice a hell of a lot more pressure in my gas cap than any other car I've seen, it could very well be that.

I'm on First and First. How can the same street intersect with itself? I must be at the nexus of the universe.

The pressure in the fuel tanks down to it being an FI car meaning that the tank ends up getting pressurised to keep a good flow going. Most FI fuel systems run at a constant pressure so in theory you should feel a drop in power right across the rev/throttle opening range if theres a leak. ie dont worry too much on that front lol.
If only I hadnt bought the bike, this would feel fast :P

Why would you feel a definite drop in power? The fuel rail is still pressurized with the regulator maintaining pressure. Unless the pump is unable to maintain flow you wouldn't notice a problem, right?

You probably "wouldnt" feel any power drop being realistic, but if you think of any pressurised system, when you get a leak in one spot you have to overcorrect for the leak (outside the fuel pumps scope since it only runs at 1 speed and does this all the time) or the system loses a percentage of its pressure which could possibly be made back if the pressure regulators set lower than the pump can provide.
As I say though, its not really something that youd need to worry about since the regulator will probably smooth any pressure drops in the fuel line let alone the fact that there has to be some kind of leak to take into acount the fact that you would otherwise create a vacuum in the fuel tank as you used the fuel in it.
Hope you can see my point (its in there somewhere lol) that unless youve got some major leak going on then it wont be a problem

Yeah, I think I understand. Basically, it's not a completely closed system to begin with, but when working correctly it does pressurize to some extent. If that pressurization doesn't happen due to a leak, the pump just has to work that much harder.

There were no drive problems with my gas cap leak (and I corner pretty hard), only real strong gas smell that I didn't like. I only mention it in case there were multiple problems and the gas smell was exclusive to the other issues.
