Missing at start-up

[EDunford]

Last week i did the maintance on my truck. Oil,filter, fuel filter. A couple of days later it began missing at all speeds. I drained the fuel filter and it cleared that problem up.

Now when i start it after it has sat for awhile it will miss for about 2 seconds then clear up.

I made sure nothing is leaking by the water seperator drain. Also there is no check engine light, the oil level is staying the same.



It has had a slight tick when it idles since it was new, but i guess that is common with these trucks.

By the way it is an 06 2500 with an auto and no mods at all. also it has 18,800 miles on the clock.



Any ideas? Could i be getting the infamous injector problem?

I would guess that when you change the filter you somehow got something past the filter to the injectors. Mine did that some time ago but it would blow blue smoke when it was missing. Took it in twice and both times they did no work on it. They did add some injector cleaner (the black bottle that they sell) and it has been ok the last 10,000 miles, the service manager also told me to add 4 ounces of two cycle outboard engine oil at each fill up, I have been about doubling that. Maybe mine just cleared up on it's own?? bg

Mine used studder a little when I fired it up after sitting for a long period (over 8 hours). It would also puff a little blue smoke. I had it back to the dealer twice and they stated both times that "we couldn't replicate the problem" so I searched on this forum and found it may be due to carbon build-up on the injector tips. I added a bottle of Sea Foam into about a 1/4 tank of fuel and ran it pretty aggressively. It cleared up the rough idle and blue smoke at start-up. I now run a mixture of Power Service (grey) and Marvel Mystery Oil with every fill-up. The truck seems much happier.

Thanks for the replies. I filled the fuel filter with sea foam and put a bottle of injector cleaner in the tank. It seems to be helping it.



Thanks
