Hey I got a 1998 Honda Civic coupe D16y8 it is throwing a code PO505 I changed the iacv already and light went off for like 2 days , but it's back now , with check engine light on if I rev to 1500 it bumps up and Down to 1600, but if I easer the code and with no engine light and I rev again to 1500 it acts normal what could this be ?
