Oxygen sensor on 94 Metro

[b65pauls]

The oxygen sensor on my 1.0 has a four-wire sensor. All the sensors I have found for a 94 so far are only 1-wire sensor. Engine has "R" ID on the block. What's up?

My bet is you have a '94 with a manual tranny. Many of these (if not all) came with "Upgraded Emissions". To get the proper O2 sensor, request one for a '95 Metro and you will get the proper part. Be prepared for sticker shock however, I believe their new cost is near $100. The last one I got for my '94 stick I pulled from a junked '96.

thanks! I LOOKED ON OXYGENSENSOR.COM. Found a Walker brand that fits 95-97 1.0 liter for $60.

Nice find! That sounds like a good deal
