I'm looking for some help. I recently installed my invidia divorced wastegate catted downpipe with my Q300 exhaust. I loaded my stage 2 map with my cobb accessport and went for a drive. I have been driving for about two weeks with no problems until today. As I was driving, my check engine light turned on, along with the traction control light illuminating and the cruise control blinking. My boost levels seemed appropriate for the map that I was running (Cobb OTS Stage 2 93). Once I got home, I checked the faults and got P0141 and P0037. I reset the ECU via the accessport and also tried reflashing the same map for the hell of it. I went for a drive, varying my driving style to see if the fault would reappear but it hasn't yet. I'm assuming because I reset the ECU that the light may just not kick in for a little while. I know it could be plausible to have had a o2 sensor go bad.... but at 26000 miles?? Has anyone had this happen to them? What was your fix? Anybody have any advice? I'm gonna lift the car up tomorrow to check the wire and clip for the o2 sensor but until then any help would be appreciated. Thanks in advance guys.
