It's interesting that the aircon under Econ works for some.
Mine was parked in the hot sun for a while and the interior was over 50C. Powered up, dial set to 21.5C, and the aircon briefly kicked in and got the temp down to about 30C then went into limp mode, fan speed 1.
Turned Econ off and immediately the fan speed went up and started cooling again. As a test, during the drive, I turned Econ back on and the fan speed dropped to 1 again and the interior started getting hotter under the full sun.
This scenario has been the same on 3 Civics and now the Jazz.
Regarding the throttle, I was on a motorway joining slip road, saw a gap to accelerate into, pressed the throttle, nothing. Turned off Econ, got throttle response back and was able to easily accelerate into the gap.
Econ, nope, not for me.
