Has anyone experienced what I call a "rough idle" on the 5.7 Hemi
in the Magnum? I had this from week one onour '05 R/Tand have been back to the dealer several times. They recognized it but couldn't do anything about it. On the third visit they called D.C.'s Star Hotline and were told the Hemis take a while to break in. It has been almost eleven thousand miles (one year) now and the same loping idle. Am I experiencing the effects of a camshaft selection by the factory or is something amiss? The dealer (surprise) is somewhat useless.
Other than this, we love the car . . . it goes like "stink".

 

Mine has always done that too.
I was told by a friend that races pro and he said,
"It's a HEMI, what do you expect" Same as cam lope.
