Getting ****ty fuel milage compared to what it was when I first got this lovely car.

My friend was behind me the other day on his motorcycle and that there was smoke comming out of the car leaving the lights....

Not losing anymore oil than normal or engine coolant so just curious wether or not the oxy is expansive...and/or the recomended replace interval.

The guy who owned my car before was a lazy fcuk so I am sure it wasn't done, if it was recomended...


...miktip don't worry you know you are a great asset to this fourm....many thanks for all you help in the past...and I am sure future...

That's for the '93-95 90 w/ the 12v-V6. I don't know if 90q in your name is the earlier version or not. I understand the interval for changing them (for those of us that keep up with this stuff - my prior owner didn't either, so I feel your pain.) is @60k's.

I haven't done any recent research, but I know the parts connection is a great place to start and if I recall correctly, they were $130 each and you'll need 2.

I think there were instructions posted a page or two ago.

Also, I've been told to stay away from those universal single wire ones, since they come with a slicer adaptor, BUT... it's one black wire and two whites. The whites are to run the left and right lead back to the computer, but if you get them wrong, I understand it fries the computer. So, if you guess wrong, you're screwed. If someone knows which one is which, then I guess the the Universal ones would be ok, but I'd stick with the 3-wire Bosch ones. I've always been a true believer in Bosch and staying with the OE part unless I can upgrade, but I don't know if there are better ones for less. doubtful. If you happen to find the Bosch ones for less, let us know. There's a list of part suppliers on www.audifans.com<ul><li><a href="http://www.thepartsconnection.com/">http://www.thepartsconnection.com/</a</li></ul>

so it is a 2.3...sweet 5...

The price on blau. ranges from $39 to $169.
Why are there two three wire sensors and almost a $100 differance in the price.

So do I need a three wire...?

Thanks,

Which is supposedly there to reduce your emissions
at start up until the cat-converter reaches operating temp.

Do you live in a state which does smog checks?
If so, do they check your car at start up?

In my Coupe I ran the 2 wire Bosch universal, and it ran fine.

The choice is yours.

I live in newfoundland canada,not very srtick...don't even have emmision testing, at least not mandatory.

I was talking to my parts guy and he said to find out how many wires it has as he could get me one at a good price, depending on the type.

I don't have alot of money as I am still off work from my bike accident, soon have the money for my s4, so I would like to go the cheapest way without any possible side-effects down the road.

It seems to be getting worse as the week goes on.
And starting to surge as was mentioned earlier.

I am going on a small road trip this weekend so want to get this done as soon as possible.

anyway thanks for all your responses....

Which one I should get, the three or the two wire one.

Does the 10v engine require a different one than the 20v...

And do I need to do any playing if i go with the two wire one..

thanks,
mike90q

3 wire has a heater which reduces emission sooner.
Do you want to reduce emissions sooner? Does your state test for emissions at start up? If No & No, go with the 2 wire!(if available for your car)
