So my car just started reading out p0171 (system too lean?), p0133 (o2 sensor slow response?) and p0303 (cylinder misfire?) codes. Oh and it seems to be a bit down on power, especially when the turbo kicks in
Im guessing the problem is the 02 sensor but after looking through the forums I'm hesitant to spend $150 on a new one, since most of the time it isn't really the problem. Any suggestions?
