Check this out...my 91 Ls (165k miles) seems to have been taken over by a demon. The battery seemed low, the radio started to fade in and out of operation and the windows were slow to operate. Then the dash lights began to flash on and off and the engin would not stay at an idle. The engin is self accelerating from 1k rpm to 2k rpm and back. I've lost all operation of the radio, side mirror adjustments, steering wheel adjustments and engin rpm. The only thing that is operating properly is the A/C.
What is going on???? I had the battery recharged and they returned.
Help!
Any suggestions on what is causing this?
