When van is turned on it idles fine. After putting it into Reverse or Drive it auto matically accelerates on its own. I have successfully gone to speeds of 70 mph with out touching the gas. When am at a complete stop it feels as if im driving with too feet one on the brake and one on the gas. After all of the driving, and im ready to put into Park. I put car into park and it idles supper high between 2 1/2 and 3 on the rpm reader.
