I set off my Check Engine Light for first time!
At lunch today while driving and was enjoying light assist while moving slow but in a high gear ... it kinda wanted to die from "chugging" and I have had a slight hint of "herky-jerky" described in threads about EGR and LAF issues. I've been planning on cleaning EGR plate anyways. I suspected this high mileage 273K gas engine might have some efficiency issues, but I never had any codes since 1 month of driving.
(I got the best MPG yet this morning on 22 mile commute- I was the most gentle EVER on loading the engine- 20 to 45 mph mostly - little 55 to 65 and got 54 MPG.)
I guess I need a Honda dealer to find out the code, right?
