I have a 2005 Ram 1500, Quad cab, with the Hemi, I can't seem to get the engine light to stay off, I've put new plugs in it, even replaced the core packs, it don't like to crank, unless it is cold, I was wondering, does anyone else having this kind of problem and if so what else is it to do? my truck only has 60000 miles on it and when it cranks it runs fine, no skipping or nothing, it shows a code something like CO300 and CO302, it says multible misfires, and misfire on # 2 cylinder. can anyone help me with this aggrevating problem ? any Help would be greatly appreciated...

When more than a 2% (2.5% LEV) misfire rate is measured during two trips. Above 3000 RPM 1 trip less than 3000 RPM 2 trip. Three good trips to turn off the MIL.

Thanks BMRFIXIT, I had a local mechanic say I may need to clean my fuel injectors, I've been adding injector cleaner with my gas,and I also thought about with this new ethenol fuel, I may be having fuel pressure leaking down..
