Civic EG

i have a 1992 civic hatch with a b18a1 swap in it
so my problem is when my car warms up the idle hunts really badly
it drops and raises about 1000 rpm until i put load on the car then it steadys out ive cleaned the fitv(fast idle thermal valve)and the iacv(idle air control valve) but it still does it
so can anyone help with this problem ive read other forums but it doesnt really specify what to do
any help would be good help
thanks aaron

Try bleeding the air out of your coolant system. Since it's happening when warm, your thermostat is probably opening which then allows the air pocket to cause problems.
