Alright, this is a follow up thread to an issue I had last winter where my 08 QCSB hemi would surge and lope when started in cold weather. The problem fixed itself because, well, winter ended. Unfortunately for me, winter is back along with my problem. This time though, I at least got video of the problem on a particularly cold day.
A few things to keep in mind:
-Bad gas is not the problem, the truck ran beautifully on the same tank until it got extremely cold.
-The truck starts right up without having to crank endless times, it just runs badly, and so I don't think the injectors are clogged/to blame here.
-Spark plugs were replaced last year at 36,000 miles with Copper NGK's.
-Throttle body was removed and cleaned last year around 36,000 miles as well.
No CEL comes on, nor does an OBDII scanner record any error codes.
-Battery is a year old and pushes something like 900CCA. Again, probably not the problem because the truck does turn over smoothly and start right up.
-Truck is on factory engine tune, no programmer.
Here's a link to the video of the problem.
