The o2 sensor is new but a cheap one off ebay and does fluctuate but spends most of its time at .9v

The car drives beautiful Andrew but the fuel gauge is moving so quick... this tank I am now in the last quarter of a tank and I have only done about 250km .

Wow. I know you know but that's shocking. So did the injectors all check out?

[Bloodyaussie]

Injectors went up to 15.00 on normal acceleration and even hit 20.00 for a nano second.

The maf voltage sits at about 1.6v on idle but 3.6 on acceleration ??

You missed the post.... I have been waiting and drooling all over my computer

[nissannewby]

I'm not a 100% certain but those voltages seem to be ok considering their operating range.

Pooh....... I was hoping for a miracle.

I have changed out 3 afm's 1 o2 sensor.. changed my ecu as the other was drowned ,new tps...

Its all I think about.... I need a life.. bwa ha ha ha!!!!

You poor bugger man, I hope you get this sorted soon. Have you thought of doing what i did and just buying a banger to get around in and tow the trailer, the repayments on it are only $65/week. Which by the sounds of it would be a lot cheaper than the fuel bill.

What temp does your engine usually run at BA? It says 78 in the pic you posted which is fairly cool. A cold engine will use more fuel. Should have an 82 degree c thermostat. Diesels run a 76 degree c thermostat.

Have you ever pulled apart the aac or what ever it's called off the back of the plenum and given it a clean? I'm not 100% on what it does, but it does play a part in changing the airflow within the engine and also changing the idle speed when you turn the ac on. They do get gummed up which will effect its operation. There's a valve or 2 on springs that can go stiff and not slide properly if dirty. Carb cleaner and brush for the win.

Normally sits at about 82-84c and I have a spare one of those acc things in mint condition. ..

Kept quiet about a booked dyno run for today and rushed around like a madman to get there by 8.30am to be told " Didn't anyone ring you the dyno is not working"...

Got told to come back in the afternoon and it would be done then.. came back and got told to ring again tomorrow morning about 10am to see??? I took the day off work for this and just got stuffed around...bloody pissed.

Billy did a fuel pressure test and it came in at about 36psi??

[Parksy]

Bugger!!

36 psi is no good. If your pump is new then the next thing would be the regulator. Sometimes you can tell if the regulator is u/s by removing the vacuum line while the engine is running. If fuel comes out, it's bad. Sometimes it can take 5 mins of running before fuel will come out. But this isn't always the case with a bad regulator, it just could be one of the symptoms.
