Ok, i dont know what the hell is wrong with my IAC, I dont even think its my IAC (brand new) thats causing the check engine light, anyways when i unplug my iac at idle she wont do anything just the same idle as when it was plugged in. So my question is since its not doing me any good and i could care less about warming her up my self, can i put a 1k resistor on the iac? its OBDII I just wanna get rid of the check engine light , my car runs great just at 1500rpms at part throttle maybe anything below 10% she'll stick to 1500rpms. then when i go over 10% throttle shell be fine. the tps is 4.75V 4.80V and it idles by itself.. Errrrrr i dont know im about to bring it to a shop b/c **** that iac
