Dear all,
D2, 5 speed, V8 (yes, it exists). Feb'2021 broke right side exhaust flange from Y pipe
Only has pre-cat O2 sensors
Had been code free for the last 15 years.
Disconnected O2 sensor connectors with utmost care. Sprayed them with contact cleaner.
After undoing rest of fixings, Y pipe fell on the floor with a loud bang (no more than 2 inches distance)
Welder welded and reinforced exhaust flange but weld was performed with both O2 sensors fitted (i did not like that)
Now idle is good, performance is low, fuel consumption is higher (but in the last 120 miles has gone better) , fuel smell in exhaust and P0130 and P0150 (O2 sensor circuit). Connectors are OK.
Oh, by the way, no CEL (Euro spec D2 don't light CEL so often)
Might have both O2 sensors died because of the fall of Y-pipe and weld?
Bur remember 15 years ago when MAF died I got the following codes
Testbook results:
P0150 and P0130- O2 sensors
P0171 Adaptative fuel mixture control Bank 1
P0174 Adaptative fuel mixture control Bank 2
too lean!
All vanished after new MAF.
Best regards
