s6 rough idle

[jimes]

I have 2000 s6 that keeps suffering rough idle. Could it be air leak as idle goes high or is it in fact O2 sensors?

I would not guess it is the sensors.. I would be looking for signal reference or something in common between the G40, G28, G163, and the O2 sensors... too many critical sensors giving false information to the controller. Got to sort that first. Once those are sorted, my guess is that the Fuel Trims will come back in line.

Did you tell us everything? Any mods made? Change anything before this happened?

clear them all
then rescan some could be old codes
