02 sensor

hi, I find that my 348 feels slightly sluggish momentarily when driving at very low revs ie. 2000-2500 in 2nd gear. Almost like the a/c compressor engaging. THough while accelerating the performance is perfect. Also, I find that off late the check engine light 1-4 is on. From past f chat threads i see that it could be an o2 sensor issue. My car runs with Tubis and cat bypass pipes. Any suggestions/advise.

 

The car I'm about to purchase has a CEL problem and the code suggests a bad 02 sensor. So, I've been looking for an online source of the OS582 sensor widely recommended on this board and I finally found a place that sells it for $99 each.

If you go the replacement route, this might be helpful.

Is there another online source for these parts that is cheaper? I found the universal Bosch part for $55 each but that requires splicing and it seems like the $44 difference would be worth a plug and play solution.

Hope this helps,

Also check to see if your throttle bodies are synchronized.

 

So on ebay stores, I found a Universal Borg wagner for $24 shipped. It does require splicing, but really, for a $75 delta I can cut a few wires...

No Doubt or someone, would that work on a 348?

 

My suggestion is to pull your error codes for that CEL.

 

Might not have the right thread pitch. Try these instead (and I in no way endorse these eBay sellers):

Before you buy the O2 sensor, clean the connectors of the O2 sensor and the Phase Sensor on the 1/4 bank side.

 

Thanks will try that or else take the splicing route!

 

ATA BOY Dean!
