Re: Burning too much petrol?!!
Bro, it sounds like you aren't getting full combustion. If you know how long ago they replaced the plugs and wires, I would do that first. If the problem doesn't go away, you might have an ignition problem and could be due to Coils, ECM, or other things that I don't know about. At least you know that your injectors are working :P.

That has the GA16DE engine, correct? From what I've seen, they are very well built.
If your ignition is good (plugs, wires, cap, rotor, etc), I'd look for a bad injector (stuck open), or a blown pressure regulator. Is the check engine light on?

Get the MAF sensor and exhaust oxygen sensors checked.
A mate had his nissan V6 running at 7:1 (lambda = 2) with a screwed up O2 sensor. Most engines would have fouled up long before then.
