I didn't say it was a "cam" problem either, but the sensation was equated with a typical hot or race cam in other words, and I just pointed out that it would do it all the time if that was the case.
If I didn't get the previous meaning exactly, then chalk it up to forum "communication".
And yes, if it was too big of a cam, then upping the idle as was mentioned would help, but I sure don't want a new car with a 1000 rpm idle!
I put new cams in my '89 SHO race car and now THAT is a hot cam idle. If a V6 can have attitude, then this car has it. And pulls strong beyond 7500 rpm. And it will have to have an idle speed close to 1000 rpm.
The idle stutter in the 300C Hemi seems to be ignition or fuel related though.
I used to own a Chassis dyno shop (was called "Dyno" Don long before that though) and when looking at a dyno chart, the smoother the chart, the better the ignition/combustion control. The best cars for this type of control? Ford. The EEC computer ignition system by far does the best job of controlling full throttle combustion. BMW, Mercedes, GM, Mopar all showed the typical spikes and valleys of inconsistent power application (combustion). It is hard to feel in the seat of the pants, but the dyno sees all, or most of all!
Still wonder if there is someplace where we can read the content of the TSB's without subscribing to something. I would like to learn more about what DC says is causing the erratic idle. It is unseemly in a modern car.
