Hi guys! Happy 4th hope you are having a great day. I was working on the Honda yesterday. The other day was not able to work on it when we were threading, I was at the fire house. Today I’m back on shift, GFD. I drove it home after shift and it drove fine with a little idle up and down. But when I got home, I knew that I had to adjust the throttle plate back at factory position and then adjust the idle mix screw. After that she runs like a charm. The E light stayed on but come to fine out code 1, o2 censer. At least that wouldn’t be a two year mystery fix. I thank you mk378 & Ron J, for you help searching the wire and diagram I knew then what to look for. It was a switching of connecters of the EVAP and the IACV. Thanks!!!

Plug the connector with the red wire into the EVAP solenoid and plug the connector with the Lt Blu/Wht wire into the IACV to see if the idle problem is fixed. The green in the Grn/Wht wire has likely faded over time to have a Lt Blu appearance.
