From a leak on the manifold I would expect rich conditions since it's pressure side.
At least when on boost, since you'd be pushing metered air out. You need to find something on the vacuum or pre-turbo side I would think.

yep... her postcat is a 4 wire, useful for swaps
but the precat in Danielle's car is probably a 5 wire aka "wideband" sensor. If so the connector plug looks entirely different... it's not compatable with the 4 wire type... not a candidate for swaps

exactly......>>>
at least you could determine if that is the issue....Danielle will get an O2S2 error when you disconnect it...but it is cleared easily...
Nice to have a few spares lying around! ;-)
