At first when I started reading what was said about the throttle issue I thought "this guy can't drive"

But I read it over again and I understand, did you ever notice that you can shift the car with the cruise control on!!!

So ya! the car is droping out the throttle when you press on the clutch!!!

The car thinks the cruise is on, I will experiment with mine and see if I notice the same thing. I have never been able to drive my crossfire as smothly as other cars. I think I might try disconecting the clutch switch to see what happens. Maybe you should too.
