Instrument Panel resets while driving
I just acquired a 1997 Park Avenue Ultra with 170,000 miles on it. It'* got several little problems, but I wanted to ask about this one first.
When you first turn on the ignition, the panel gauges go through a check and all the warning lights come on. My problem seems to be that this will also happen occasionally while driving. Is this controlled by the computer, is it a wiring problem in the dash or at the computer?
I have checked for water/corrosion problems in the floorboard similar to the issues we have had on our bonnevilles, but everything seems dry.
Other problems I have yet to address:
replace oil pressure sender
replace */C coupler
driver seat electric controls don't work (looks to be a bear to remove)
oil leak around front valve cover gasket
fuel level sender (guage is erratic)
My FSM from Helm is on the way!
