Default 2007 300, ALL 6 cylinders misfiring

I have a Chrysler 300 v6 that is giving me a misfire ofALL 6 cylinders at the same time. This usually happens on the highway or when I am picking up speed. I have brought it to a Chrysler dealershipand my local garage and no one can give me answers. 2 of the coils are new andmy sparkplugs are all new. My check engine light does not always come on and iscurrently not on, so they cannot check for codes. In the past the codes haveread bad coil on #2 and #5, which are the two I have replaced. Those two stillmisfire, along with the rest. I have also had my camshaft sensor changed. Can someone please give me and answer as to what may be causing thisproblem. It is incredibly irritating! Thank you in advance!

I have a 06 300 with the 3.5 and I get a random P0300 and I also get P0301 but I changed the #1 coil, injector, and all the plugs have less than 4000 miles ... the dealer wants me to change the upper plenum before they can ck for the misfire but it's really hard to find one and a new one cost $1800

nickincam, did you discover the problem? My 2008 300 Touring has a similar problem when picking up speed or going up a hill, it jerks quite a bit, wasn't sure at first if it was a transmission issue or ignition issue but I think its missing. I changed the plugs today and no change at all. No codes are shown either and I'm worried about taking it to a dealer for fear of part swapping to try and figure it out.
