mild weather like 40 to 50 degrees i wait for the wait to start lite goes out and start the truck i know the grid heaters come on when the the little battery gage goes down but every once in awhile i get a bad stumble like the truck misses a lick when the battery hand starts to move. only does it at idle Dealer cant duplicate. No codes stored. should i worry about it. fuel filter has about 8k miles on it.

 

Mine did the same thing the other morning, I'm not sure what caused it but it drives fine and idled fine after warm up. I'm not gonna worry about it right now.

 

I'm guessing its normal...Mine stumbles maybe once or twice(but only for a split second) on the first cold start on cold mornings. My buddy has the same truck, and his does it too.

 

well at least i am not the only one with must be kinda common. every thing i think isnt right i do a search on here and it comes out to be normal. Thanks dtr
