So I have noticed that when it gets cold my truck stinks on start up and it still kind of stinks until it reaches its "running" temp you could say. I have a Air Intake, Tune exhaust and Oil Catch can. Is it the change in gas for the winter, bad plug? Any ideas?

Its hard to say, kind of like eggs,

The catalytic converter kinda smells like rotten eggs when it starts to go!

True, could it be the heavier air in the winter which is why I can smell it? The does almost have almost 90k on it

I don't think air or fuel would make any difference, the cat would be my guess.

Last night and my check engine light comes on, so I stopped at Auto Zone this morning so they can check it and reset it and now I have a P0151 Low voltage Bank 2 Sensor 1 issue. So my )2 sensor is bad or my cat is shot which I tend to believe the issue is. ( I have another thread open about a stinky smell and someone suggested cat issue). Looking on here the P0151 is the drivers side )2 sensor correct? So I would assume its the cat needing replacement since I heard a noise or should I start with sensor?

Like I said before, it's the cat "Bank 1 is where the Number 1 cylinder is located. This is always the forward most cylinder. So then if your diagnostic code is B1 S2 that means Bank 1 Sensor 2 downstream (post-cat)"
