Not going to start an arguement here.... but that is NOT true at all. It says right in your owners manual... page 88.... "Allow engine to warm up at least one or two minutes before moving".
All of the e-techs will shut down after 12 minutes except the ace.. those are 5 minutes. They should even be moved after idling for at least a few minutes.... them pull them out and let them run.
Im not going to argue ither,, I do it every day and haven;t lost a Etec motor yet.
