knock at idle only?
I finally got some logs of my car and it seems I have the occasional knock at idle...not at any other load or RPM, just at idle. This seems to correspond with a slight rise in RPM's and a bit more of a lean condition on the WB 02. Any idea? Car is just stage 2 cobb with full TBE and catless UP. Also has a new TMIC, but has been exibiting the same since before the TMIC.

Mine too. Seems like some kind of transient thing. Perhaps something about the motion or vibration of an idling engine fools the sensor.

haha, ok...silly, but I just heard from one of our locals that the guy that tuned for him, guy named Scott Seigel out of Subaru of Gwinnett, that it was like a false knock and not to be concerned.
