Code 0505
Hi guys and gals, well intermittently, my check engine light comes on. Every morning when i go to start my car, it idles at 2000 rpm then when it warms up it idles from 1000 rpm and bounces to 1800 rpm (up and down) then sometimes when i stop at a light it will idle at about 1500 rpm and the CEL will come on showing code 0505 (IACV malfunction). I've just changed the IACV and it idles better but the problem still exist's... Can any please help......
