i have a 95 civic ex..just recently i have started having problems wtih my idle running low when my engine is warmed up.it is fine as long as i am driving but when i stop at traffic lights when i slow down it surges to 1200 rpm and then starts dropping as i stop. my idle drops real low like my car is gonna die but it never does...i checked my vacum hoses for leaks, changed my pcv valve and fuel filter,but the problem presists..any help would be appreciated....
