Hi I have a 91 LE with 141.5k miles. I noticed recently after I turn off the car I get a rhythmicc noise. Sometimes it happens 5 seconds after the car has been turned off. I'm not sure how to describe the noise. It definitely has a rhythm/pattern to the noise. It slowly winds down and then stops after 5 - 10 seconds.
It sort of sounds like there is something moving in a circular fashion (kind of like a dryer drum) and there is something that brush or slides every half second or so. I haven't been able to isolate exactly where it'* coming from. It'* coming from under the hood obviously.
At first I thought it might have been a spun bearing, but I'm not experiencing any knocks. So it probably isn't that. But that was the first thing that came to mind when I heard the noise. Like I said the odd thing is that the car is off.
The other thing I noticed is that the car has recently started to "huff." After about 30min - 1hr of driving, it goes away. I thought it might be loose belts, but they seem fine. I'm not sure if the two things are related.
I'm sorry for the lack of description/words. I'm actually half way decent with cars. Obviously, I've hit a section that I don't know
