I spent all of Friday trying to diagnose the issue with my wideband O2 setup.
Rewiring the thing, spent an hour on the phone with them, etc. etc.
After all that, it ended up being an exhaust leak at the driver's side collector. A pretty significant one. The flange was warped/bent a bit and wasn't sitting right against the header collector.
Spent Saturday after noon dropping the front of the exhaust and whatnot with what little time I had. I have to weld a new flange on the downpipe on that side but then my O2 sensor should be working and I'll be able to get a legitimate tune on the thing.
Still have to fix my bender and my tent.
