I am pretty sure that it is your ABS boost pump that is going.
I have a 91...after i have driven a few miles and go around a cloverleaf ramp,
my brake light comes on also. There is no reduction in braking at all....just
the light on the dash. I have been told by several people that the pump is
slowly going out and will probably need to be replaced soon. I have had this
situation for two years now and it keeps on ticking...go figure.
I have been told that there are two different boost pumps that were installed
in these late Imperials. One made by Bosch and the other by Bendix. The Bosch
pump is the expensive one to replace. It has been suggested that I completly
get rid of the ABS system and install a non abs from a New Yorker or a Dynasty.
In regard to your air ride system. Buko bucks to fix. I had the same problem
in my 91. The front struts finally gave up the ghost. I checked into replacing
them, but, the only place I could find them was at a Chrysler dealer. $927.00
each. I love my 91...but that was out of the question.
I went to my local mechanic, and he told me that he had done several
conversions to a conventional suspension. I ended up using the front struts
and and all the mounting brackets and stuff from a 90 Dyansty.
For the rears I...he installed a set of Gabriel hi-jackers air shocks.
All told ...it cost me about $650.00 and it rides like a dream. I cannot tell
any difference at all in the ride.
Hope that helps
