Does this look like the plug on yours? If so a cheap solution:

I'm sure the above is right but I can check my o2 sensor for a part number next time I go to my workshop, I have 2 sitting on a shelf.

Jestem pewien, że powyższe informacje są prawidłowe, ale mogę sprawdzić mój czujnik O2 pod kątem numeru części, kiedy następnym razem pójdę do warsztatu, mam 2 siedzące na półce.

I would be very grateful. Do you know, is that posibble to show error 34 after o2 sensor fault? Or its two other issues?

Can you show a knock sensor at engine? i cant see it, is it under plenum? or under down manifold?

I am 99% sure it's in the valley under the plenum, I"ll have a look when I go in as I have the plenum off already.  As for your code question sorry can't help you there, I do not use the stock ecu and I've never scanned it.

I have last question  tommorow i wil replace my o2 sensor. But from ecu i have red black and white wire and from sensor black, white, white. How do it?

[KitsuneY33]

Is that correct connect? 

[KitsuneY33]

I replace O2 sensor and its ok. But i still have code 34 -_-. Any suggestions?
