have you tested your o2's? you can do it using a voltmeter or using consult/datascan. you just need to make sure they're nice and responsive and that the voltage output should sweep from low to high about once a second. datascan or consult is easiest coz it will just display the voltage output for you. just make sure your car is at operating temp and you'll need to rev to about 2000rpm when you're measuring the voltages.

yea freind of mine hsa consult but he is currently at albury he should be back in bout 2 weeks il run the car thorugh that then. but it seems to be ok now, have to wait and run a full tank first to see.

he also has a NA zed :P

how many o2 sensors need to be changed?, there that 1 that goes into extractors and another that goes into cat. change BOTH, or just the 1 that goes into extractors?!

There's only one O2 sensor (in the extractors), the one down near the cat is an exhaust temp sensor.

check out Kudos in the trader section for good cheap O2 sensors

I do not believe the sensor near the cat relates to how much fuel you use, I run my car without this sensor and it has no issues.

I also believe its a temperature sensor, not an O2 sensor....

im confused, how come it seems like the more i put my foot down, the better fuel econ it is??

the for past month, i been driving like a grandma and my car drank 10.8 - 11.2L/100km

but last week, i was having some fun in the car, and the car only needed 10.2L/100km.

can any1 tell me why?... and is it true that it saves petrol if you change gear at about 2000 revs?

too many variables for such a small difference.

are you measuring ambient temperatures while you're doing this?

the quality of the fuel?

how did you calculate the fuel usage?

for the whole time, i been putting in V Power.

i calculated by L of petrol divide by mileage, thats right...isnt it?...

The draft Fuel Consumption Information Rule proposes that importers of light vehicles provide accurate and reliable fuel consumption information and seeks to clarify how this information is collected.

      @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?

      Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s

      It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
