1. I did not check the plugs yet. Will do that asap.
2. Still would like to know what is everyone else's idle speed is.
3. Let me ask the following: You know how your car starts to roll when you release the brake without depressing the accelerator pedal? Well my crossfire hesitates to roll even down hill! My driveway slopes down towards the street and as I start the car, release the brakes, I almost have to press the accelerator pedal to go down the hill!!! Is this normal? Even driving down the highway as I let go of the accelerator the car reduces speed at what seems to be faster than normal pace. My Chevy Malibu LTZ for example, as accelerator is released, the speed is reduced very gradually, you don't feel it almost (provided you're on a straight horizontal stretch of road of course).
