the check engine light turns on and i checked it with a scanner and it said that the idle speed control sensor was malfunctioning. The part was broken but i replaced it. I erased the code but it still seems to come up over again. What else could be wrong? any help would be appreciated. The cables are good and so is the socket. I checked the ISC valve had a resistance of 9.5. Does anyone know if that's the right resistance?
