The CEL have never turned on, even when the engine idles rough at start-up.
It only occurs at start up. Never at a light.
I understand your logic, that it could be a sensor. Throttle position sensor maybe?
By scan, do you mean with my Peake Tool or another tool or maybe at the dealership.
Thank you for your input Drewfus2101.
