Hi was hoping someone might be able to help,  I had the engine light on my 2004 Impreza come on,  the fault code was front o2 sensor,  I've had this replaced but since the light sill comes on and from time to time it jolts a little add if it's misfiring but soon clears itself

 

Tia for any help

Was it a genuine sensor? I've had alot of issues with knock offs or cheap ones before

Hi, it was one from Ebay,  looks exactly the same just not denso

I'd probably start there then and fit a genuine one

I got a denso 02 sensor on my last wrx and it wasnt that expensive think it was from opie oils
