ISC motor testing 33 ohms, but doesn't make a difference in idle if unplugged?

[adam355]

So it tested good, but if I unplug it the car runs the same? I dont get it. Anyways the reason I'm checking it is because I have a terrible cold idle. So what do you guys think? Shouldn't the car idle different if the isc is unplugged? Thanks

Technically, the car should die when you unplug it. Try taking out the ISC and cleaning it w/ some carb cleaner. I took the lazy way out and sprayed carb cleaner in the throttle body. Worked for about a day, but its back to the same shit so im just gonna replace it.

Thanks dude, I think I'm just gonna order a newly rebuilt one.

Don't throw it out. Mail it to me! I'll use it when mine goes. 33 ohms is a very good read. There's noting wrong with it. Just take it out of the throttle body and clean it with carb or throttle body cleaner.

Alright I will try that. Thanks

Why is that?
If the car runs with it plugged in and you unplug it the ISC pintle doesn't move from where it was, so the same amount of air that was bypassing throught the ISC continues.

Good point. I did some research after the fact and saw that the car doesnt die. My answer was coming from the old ford probe turbos i used to mess with. My uncle used to be a ford mechanic i used to work w/ him in his garage and learn. Those probe turbos used to die w/ the ISC unplugged which pointed to a faulty ISC. Thanks for the correction tho.
