For some time (about a year) I am experiencing surge/stall/bog problems.
I have changed the spark plugs, spark plugs wires, ignition coil, cleaned the throttle body... nothing changed.
Unfortunately, here in Romania, the electronic diagnostics is very poor for Subaru (as the car is very rare), the car shops don't have the software to dig deeper on the problem.
After reading this thread and other similar here I have decided to change the front O2 sensor. My mechanic does not think that this will do it but I have insisted.
The problem is that there aren't much options for the parts as well here so the one I found on stock is one from Denso without the connector. This would not be a problem cause I found the wiring diagram but my mechanic says that those two sensors are not the same.
The one that I bought is called Lamda sensor in Europe and was what the dealer software found for the precat oxygen sensor for my car and it looks like the one in picture 1 and the one from the car looks like the one in picture 2. I did not manage to get a picture of them both because I blackout when they said that it's not the same thing. Can anyone tell me if I can use the one I bought?
Also guys I want to ask you all to excuse me because I will post this on few similar threats to try to obtain as many answers as I can.
