The car was running kind of rough and at idle the rpm would fluctuate from about 500-1500rpm. I think its the iac but my dad cleaned it today while I was gone and he said it didnt work. Cleaned it with some brakleen and he said it was still doing the same thing. When he pulled line off for it he said it idle around 1000rpm and seemed pretty steady there. Is the Iac just completely shot? Or any other ideas? Thanks.
