Just tried to do the o2 sensor diagnostic in an effort to solve my longstanding overfuelling, rough running problems and I can't get any result. Am I doing the test right? :confused:

 

1) Warm engine up

2) Take to 2000rpm

3) Turn screw on ecu same way as when doing ecu diagnostic

 

The led is doing nothing at all - it stays off completely. Now am I doing the test wrong or are my o2 sensors up the spout? If the sensors are indeed up the spout, how much do they cost and are they a diy job?

 

Answers on a postcard please (seriously, any help would be great! :D )

Thanks for that vijay, I'd seen the twinturbo.net faq but not the ttzd.com. The ttzd.com is more explicit in how to do it.

 

:duffer:
