What are you basing that on. The colour of the spark plugs? They should be a ceramic colour but with efi spark plug readings aren't much value anyway.

I'd be looking at the exhaust first, if the cats have collapsed or are blocked, everything upstream will suffer.
On the fuel burn side of things, if its going through that much fuel start looking at the maf and hego's as well. if it was lean then it would be light on fuel no heavy on fuel.

Blocked cat is a real probability. Or failed hego's.
