2006 Engine miss

[hearingyourlies]

OK, i'll describe the best I can.



When it' cold, the truck automatically goes up to about 1000 RPM. From about 1000-1200 RPM's (when the high idle is adjusted), it sounds like there is a miss. The best way to describe it is it sounds like my 04 hemi's idle when it had a bad plug - like a cylinider dropping out or a vehicle with a crazy cam. Over 1200 RPM's it seems to go away. This is only while in park, too. I haven't noticed an obscene amount of white smoke or a loss of power.



Is this an injector? If so, would this be covered under warranty at 42k?



Thanks guys.

Nobody? It seemed to disappear with the temperature outside being around 55 or so ... .

Does it go away after the truck has warmed up?

I'm having the same problem with an intermittant miss at idle. It seems like mine started after running a few tanks of B20 fuel, but it could just be a coincidence.

Mine has been like this for a couple months now, and I've been watching the oil level closely. I think it's probably injectors as well, but I'm not sure. I'm out of warranty though (due to mileage and add-ons ), so I'm saving for a set of Flux 1. 8s.
