My truck has a miss when you first start it in the morning. Also on the interstate at 65-70 in 6th gear there is a miss. Does anyone else have these symptoms? My truck has 998 miles on it. Thanks for anyones help.

Your truck needs a visit to the dealer! btw what model and engine?

I have a 2012 with 2600 miles that runs rough when its first started also has the condensation problem. I think these problems are just the nature of the beast and all will be affected under the right conditions.

Thanks for the info but still doesn't help at all. I am using the mobile app for the forum so I can't see his "sig". I won't ask for it if I could see it.

For the missing so far it seems like it is usually the injector on cylinder 6 and most often a catalytic converter needs replaced but most are getting a code thrown in the computer. Also this usually happens under a load and acceleration where the truck looses all power. Since you have the IC issue I think most likely the group you'll fall in; just will take time for it to get enough misses on a cylinder to throw a code. Take it in to the dealer and they can check misfires on each cylinder.

Are you experiencing a extreme decrease in mileage?

My mileage hasn't been good since day 1. Overall average at this point is 14.1

My 2012 has the same rough idle only on the first start up of the day. It last about 1 min. or so. It has done it since new 19miles. I think its just the way the direct injected engines run. But other than that I am cool with the way it runs.
