Driving 2-3k Rpms And I Go Through 1/4 Tank In 20 Mins.....huh?

[gts-4 dreamer]

im thinking i've got a problem, new tank of fuel and to test out how economically i can cruise her i hobble along @ 2-3k rpms changeing up @ 3k and dropping @ 2k, like a really slow wanabe rally driver

anyway

it was a cold night, i got home from work and the misses gives me the movies and hte keys soon as i step in the door, ah well, guess i wanted to cruise anyway and getting into her anties was gona be allot easier without arguing about silly shit so i jump in, drop the movies an leave it idling, jump back in an look at the petty gauge is on half after 2 days from a tank and like 1 half hour juant the night before, anyways i decide i wana see if she is ever gona be any good for daily shit, so pump some tunes and drive the speed limit, every wanker and even a gran fly past me in my beast of a looker purring along.

anyways take to laps around a major concuorse get far gone bored and hed home, looky looky 1/4 a tank is gone.... get the shits with it, take her out the back to a deserted street i know all to well, actually a dead end whith 1 house at teh beginning of hte street and a nice empty clear run for just over 1 click, perfect spot for playing 2 quater practices, anyways launch of boost (not to big frying her stupid) in first she moves, is 5-6m down the road bang on boost peak her to 6k up, stays above 4.5k in second, then 3rd, an she drops to 4k and 5psi instead of 7, by this time im pretty much half way, time for brakes, and hear literaly a buble bloe (not a bang or ping as is described but like a buble then like its clearing its throat) seems to happen when ever she's warm and ive floored the ol go pedal.

sounds like it comes from the rear end like out of the exhuast so im thinking its unspent fuel igniting?

if thats so, that would explain the shitness of my L per K's, she runs f**king rich ?

cuase no boost gage, just teh stock mercury measurement which sits on + 3/4 @ full boost. think thats the 7psi 2nd stage ?

she's got a 2" cat back exhuast and essentially completely stock mechanically bar my constantly on HICAS light, pretty sure that wasnt turned on constantly stock !

you guys get better mileage than that or is that about on par and im just gona have to get used to my 250k's per tank of mixed spirited driving and cruising?

is there a puddle of fuel under your car on your drive way in the morning.... thats the first thing i'd check

If u push it drinks... but still with spirited driving on BP Ultimate I get anywhere between 400-450...

Much less on Optimax.

My fuel gauge does funny things and goes up and down a fair bit. Best way to tell for me is the number of kays i've done, and how many litres the car takes at the bowser.

Yeah..... so could I....

when I had a broken diaphragm in my fuel pressure regulator.

How the hell do you go through 15+ litres of fuel in 5 minutes?

By having your car drink around 30 Litres per 100 Km... lol

dont know about the noises but I'd check the O'2 sensor my car started to idle a little funny and start drinking LOTS of fuel (250km a tank!!). checked out the engine bay and the wires to the O'2 sensor were all melted. But its a problem u wanna find and fix fast coz evey time u drive that car its a lot of money down the drain.

you're right, you do have a problem.

but other than that.

I'd just take it in, could be a number of things

[gts-4 dreamer]

no puddles under the heh, running her on bp ultimate only since recieveing the car, so yea, feeling the pinch.

nobody ever hear like a glug sound while driving come from the exhuast after she's warm ?

after she's warm shes fine idling unless i give her a light push on the pdle, watch the tack bump from idle on .9krpm to 2k rpm and she stalls, happened a few times just after getting her.

going in to get some stuff checked by the importer on my 3 month warranty, the front window spray pump is gona and she is starting to make a sound like the fan belt is to tight after warming up, like a cog is squeeky maybe... eh dunno
