So I just put new o2 sensors in the truck this August and today while runnin a few errands, my check engine light comes on. Long story short, each code is o2 related (P0140, P0141, P0154, P0155) and I don't want to just keep throwing sensors at it. My only guess as to why they made have gone bad is the truck ran way rich after installing the new cam, but probably only went 20 miles or so without a tune. Also they are Bosh sensors, if that has anything to do with anything. I just wanna get this thing running right before it gets to cold to work on it.

after my cam install and bigger injectors my cold start was to rich...my o2's only lasted a few months....make sure cold start isn't to rich

It was running way rich pre tune, but I really didn't drive it all that much. Hopefully once I get new ones in it calms down and runs a bit better.
