1991 INTL REST light gone crazy

[billschroeder5842]

My INFL REST light comes on and off intermittently with no apparent reason on my 91.

There seems to be no rhyme or reason. I can start the car, watch the flashes go off drive it and it sometimes comes on. A few more miles, and it may go off or stay on-- you pick. Most of the time I don't see it and everything is normal, but every now and then It pops out of no where.

Also, the car seems to reset itself when I turn it off and/or go through a new start cycle again.

Now, I've read about the 90s having issues and the fix was made for 91. I read that due to the location of the sensors, they are prone to corrosion and the fix is to pull them off, clean the surfaces and reinstall.

I've also read that the code need to be cleared, but the light goes off. Does the system store the code or does it disappear?

Any ideas?
