Thanks for all the feed back.
Billydpowell, you make a good point. I could put the pressure gauge on and not get a low reading since it only happens sometimes.
Might just look into changing the the pressure switch.
Thanks for your comments. Because I know the previous owner of the car I am going to assume there is no sludge build up because they kept the car well maintained and had the oil changed regularly.
I might try to change the oil pressure sensor and see what happens. Can you give me an idea of where it is and if there is anything I need to know about changing it? Does the oil need to drained before doing this?
If that does not work can you tell me how to hook up an oil pressure gauge? And can you recommend any brand in particular.
Thanks for all your help.
The normal light on the dash keeps flashing even when I switch from normal to hi on the console switch and the car does not respond. The hight goes up and down on its own with no discernable pattern some times one side goes up or down or the other side or both and mostly in the rear. When it goes down all the way it looks like a low rider in the rear.
My 1992 ls 400 suspension height system not working as it should. The normal light on the dash flashes even when I press the hi or normal switch on the console and the car does not respond. The car goes up and down on its own with no discernible pattern. Some times one side or the other or both sides and mostly in the rear. When it goes completely low it looks like a low rider in the back
