02 Sensor

Anyone know a good place to find the front 02 sensor for a decent price. I've checked oxygensensors.com and the front 02 was $200 (That seems insane to me considing a Wideband is only 350.00). Thanks in advance for any help.

Try http://www.subarugenuineparts.com, do you have a part number for it?

Yeah, subarugenuineparts is going to have the lowest OEM prices that you can find.

Try 1stsubaruparts.com, too. You might also want to check the part number for the rear o2 sensor.. Maybe it's the same?

Wish it was, I would just swap em (rear one doesn't do anything anymore :wink:

)

The rear is a narrow band ($50.00) the front is a WideBand (not in the sense that we need for tunning) but still a wideband none the less. I suppose thats why the price is so high.

Thanks for all the suggestions you guys helped me out alot.

- Couldn't get ahold of the other places so I just order from here. They were very help and plesant. They did make a comment about how on modified cars the 02's go back quickly. Wonder why?

if it works, and it's cheap, why not?

As the sensor gets older you would expect the readings to become less and less acurate.

I agree, probally not one of those parts you want to buy used.

In my case the 02 sensor didn't seem to be the problem. I get the same readings with the new one that I got with the old one. So at this point I'm starting to run out of ideas. The only other thing I can think of is the manifold gaskets or the uppipe gaskets. I'll be installing a new turbo soon so I replace all the gaskets when I install that. Think it's time to start tinkering with injector scaling for now.

Sucks

Have you tried running some injector cleaner with a tank of gas? Maybe they're just a bit clogged.

I've used seafoam (supposed to be an injector cleaner right?) Didn't seem to make a changed. The whole intake track was pressurized and I couldn't find any leaks. I swapped out mafs with a car that was running less than 5% A/F Learning and no change in my readings.

So the only thing left could be the gaskets.? IF you have any other ideas, I'm listing!

Seafoam cleans the intake and doesn't do anything to the injectors though, right?

I don't know what gaskets could cause any problems.. have you checked your fuel pressure?

Jeramie · **Posted:** Wed May 10, 2006 9:46 am

SeaFoam you are supposed to put in intake (via vacume line) in fuel (to clean injectors) and in crank case oil to clean bottom side of motor. Last time I used it, I did all of the above.

I could try injector cleaner (just seems like snake juice to me).

No I haven't checked fuel pressure. I don't have any way to do that. Maybe time to buy some more tools.

I also haven't gotten around to doing a compression check yet.
