ah, okay. Well there are a dozen other things on that site, some of which you've already ruled out (including the one I told you about but didn't see in your OP, sorry). Good luck dude.
There is some good info here:

It won't throw a code because I believe the ECU is seeing normal readings that require a ton of fuel to be sent to the engine. Could be your TPS; check to see it's reading 0.5V at idle (it'll read 5V at WOT).
