See first post, I changed everything.

Now i looked visually, for any potential bad ground. All looks normal. But there's lots of grounds in there. Is there any one that has been known to be problematic? so I can verify alls good.

Again this hesitation is on a cold engine mostly (in mornings). What things could be sticky when cold like Throttle Pos Sens. I don't have much experience with newer cars with all these sensors. I hear from honda that if the O2 sens is bad it will cause a fault and click on the engine light. Which we dhave had the light on twice now and it has gone off after a week both times. Can you guys make anything of this?

Thanks for any advice,
