It's not closing properly mean little bit air leaks on the other side normally it should completely close and properly sit on its seat but today when my mechanic was cleaning it and he observed it was leaking air on the other side while he was spraying with carb spray. I have slightly idle issues ...
My idle stays at 900-1000 without ac, when ac on it drops until 500 and slight come back to 1000 again, I think it should happen very fastly but it takes little longer, this causes engine to vibrate and sudden drop in speed while driving when ac cut in cut off.
