Hi,
I am trying to use my pscan diagnose high CO emissions on my 98 R400 1.4

Fast Idle 0.669
2nd Fast idle 0.658
Nat Idle 0.801

Lambda and HC are ok.

The ECU goes into closed loop, the oxygen sensor voltage varies mainly between 0.1 and 0.8 and the temp sensor goes up, from memory ECU reads 90 dash is just under half way.

A couple of questions,
What is the 'normal' operating temp of the engine?
and if I were to average all the O2 sensor voltages should it be near 0.45v if its working correctly?

currently the engine seems to sit in the high 80s and my average voltages come to 0.35 ish

Cheers

Neil
