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.

First, I order to get reasonable answers you should advise how many miles you have and any modes have been installed. Also, what has your shop said they think it could be.

148,000kms, no mods, and my shop thought its was an ignition problem. They then checked my ignition system and found no problems.
So im back to square one......

check tightness of plugs and wires when cold

I had that code and tried a fuel system cleaner - dirty injector. That worked for me.

Get the clean with the highest PEA you can find.
