stutter/stumble
This started happing during the cold months, but continues now with temps in the 70s/80s.
My truck will stutter/stumble while driving until it reaches operating temp. Once its at operating temp, its usually fine for the rest of the day, but if I leave it for 6-8 hrs and its able to cool off, it will do it again until it warms up. Stock or tuned, doesn't matter. Seems to do it more noticably when going up a slight grade or accelerating at around 45-55 mph.
Any ideas?
111K miles, 06 auto. see sig for the rest of info.
Oh, running 5 40 syn oil.

Thanks brickie. That seems to be my problem. I am going to do 2 things. I just ordered a bottle of HSS and am going to change my oil as soon as it gets here. 2nd, I am going to change oil every 5k, instead of 7k. I do a lot of city driving, and maybe changing my oil on the 5k schedule will help. I already run good oil (Rotella syn). Thanks for the reply.
