I suppose fuel could be the issue. Its funny you mention that because today when I had the hood open after I turned the engine off, there was a buzzz...buzzz...buzzz... coming from the charcoal canister. Dunno wtf that was all about. However, if it were a fuel delivery issue I don't think it would run perfect off idle, which it does.

did you pb blaster it first and then use an o2 sensor socket?


Well this 02 has the flange with two studs. I literally rounded off the nuts with my fingers, it was hopeless to get them off. I swear... the only rusty spot on the truck, figures its what I needa change.
