After searching I couldn't find a conclusive answer on how to determine if your ISC is faulty or needs resetting.

I just noticed that the car is bogging down when the radiator fans comes on, further testing revealed that it does the same for the AC. I think the culprit is the ISC.

I read somewhere here that sometimes the ISC motor goes out of range and basically needs to be reset. How is that done?

I also read that I could just give it time to fix itself but what if the ISC is faulty? I might be waiting in vain. Is there a test to determine if the ISC is faulty?

Thanks in advance..................

 

OK, I'll bite. WTF is an ISC?

 

Idle Speed Controller.

It's an ECU driven step motor that controls the idle speed by moving in-out and blocking an air passage.

 

Anyone?

 

If it exists here, please let me know. If not, HEELLLPPPPPPPPPPPPPP!!!!!

 

 

Buy the shop manual. ISC's are usually tested with a digital multimeter (measuring resistance in Ohms) between the various internal coils. If the resistance is out of spec, you'll have to pay satan boku $ to get a new one.
