Lads,

I have changed the 02 sensors in the car and the operation seems to be a success with better low end driveability. Too early to tell just yet. Two questions:

1) Do I have to disconnect the battery for a period of time so that the computer works better with the new sensors? Is that just a stock EECIV thing? I have AUII, so my computer is EECV.

2) If yes to above, and even *more* important. If I do disconnect the battery, will this upset my UniChip programming? I don't have any of the UniChip doco with me, so can I assume that the EEPROM can survive an extended power disconnect (if that is required)?

Don't know about the Unichip bit but discionnecting the battery will help the computer relearn faster. However, if you give it some time it will do the same thing in good enough time.

Yeah it will learn over time.
Just belt it up Mt Nebo mate, I know ya want too!

I think the Unichip programming will be fine, but as others have said, its probably just easier and safer to let it learn itself, usually takes 1-200kms.

Well Gav, if that is what it takes, I suppose that I will have to force myself to do it…

Being impatient, I did just disconnect the battery for an hour. When re-connected, I tried to start the car. All the lights on the dash came on and… absolutely nothing! Having completely shat myself, I tried again and she burst into life.

Anyway, the car seems to be smoother when running under light loads. It's nasty habit of jerking around when using cruise (when teetering on the light load / trailing throttle brink) has gone as well. Big thanks to Marcus (aka AUGhiaV8) for his help.

whereabouts are the o2 sensors located??

how much are they to replace??

svo347

Located before the cats, trace back you'll find em, can be x amount of distance due to the differences if Extractor brands etc..
What was the cost mate cause Im sure mine are due for replacement..
$140 ea??

I did mine not long ago, they were just under $100 ea, from Repco.
May be able to get them cheaper else where, but I couldn't be bothered for a few bux.
They were physically different but they work the same.

On a tip from Marcus, I got mine from AutoBarn for ~$240 the pair. They are ACA brand (Automotive Computers Australia).

AUGhiaV8

E-series have 3 wire... from what I can see a bit cheaper that the AUs which are 4 wire.

Prices vary wildly no matter where you are. I got my 4 wires for $228 the pair about 5 months ago and was quoted up to as much as $350 a pair at some places (or $340 EACH from you know who!!!!!!!)

I reckon any 3 wires (E-series) for $220 a pair or any 4 wire for $240 a pair and you're doin' OK. I have heard of the 4 wires at some places in Sydney for as low as $90 each but that was a while ago.

As Slipper says, he got his for $240 for the pair, mine were $228 about 5 months ago, dodgies were about $195 a pair for the 3 wires... so about that I guess these days. These were all ACAs or NTKs. Just give Repco, Autobarn or Supercheap a call.
