Yeah, I know that. For some reason I was thinking all plumbing was removed including the valve itself. Durrr..

Anyway, OP, did you try unplugging the 02 yet? If it runs better with it unplugged, then the 02 sensor is the issue.

I also looked at your logs and the timing is all over the place and your corrections were way high at idle. Don't really know if the TPS is causing that or not....
