OK, I will go ahead and replace the upstream sensors. They are pricier than the downstreams, so I will do some eBay shopping.

Thanks for the link, looks like a good thread. Will view in detail after I get off work this evening. Yes, I have been reading and watching youtubes on fuel trims, trying to get my head wrapped around it all.

I did notice the high LTFT on Bank 2. So, maybe I need to go snooping around all my hoses and air intake, etc. Wonder also if that lean condition could be caused by a fuel system problem. I would have thought that would trigger some kind of fuel system code, but maybe not, I don't know if it has any way to sense that. Maybe a bottle of Techron would be worth a shot.

Not sure if OBD Fusion does the vanos test. I will check on it.

Thanks!
