Honda city auto 2006 Problem is on ac when I'm driving the rpm goes to 2,2.5 or 3 and as soon I remove my foot from pedal to slow down or brake the rpm drops very very quickly to 0.9 or 1. Idk if it's something related to changing gears or what also the fuel avg of car is also very very bad
please visit a automotive aircon shop, ask them to check the "idle-up" vaccum tube line.
if you mention your city there may be trusted help near you.
