P0300 only in cold weather?!?!?!

[Peddle021]

Hey everyone!
Im new to the site, so please bare with me.

My 2011 Ram 1500 5.7 has been throwing a P0300 code, but only in cold temps (-15c to -30c). Also the truck will stall while coming to a stop. But again, only in these cold temps. I have found that putting the truck into neutral while stopping keeps it from staulling.
Spark plugs were changed in Sept. Coils were checked by my local shop recently.

Also i should add that i had this problem last winter as well.
Any help will be greatly appreciated!

Thanks.

I had same problem. I have HEMIFEVER 89 octane tune, I put in 89 esso gas, AND P0300 came up. I find ESSO gas is crap. it is the Weather and gas combination.

I only use Shell gasoline.
Im wondering if because the truck doesnt stall when i shift into neutral, would that suggest a sensor?
