Hello i am not sure if this is the correct location to post this , my CEL recetly came on a few days go on my 04 legacy. When I got the code read it was p0030.
i read things stating its bad also just a malfunction in b1s1. When I called a mechanic they wanted $500 to repair it.
I know its before the catalytic converter, the one thing i cannot seem to see is it able to be changed from the top of the engine. Not having to get underneath the car. Also how easy it would be to do on my own with little to no experience.
Thank you.
