First of all Its A 1992 500 SEL.
It happens on the Freeway at speeds of 70-80 MPH and when it does there is a complete loss of power, stiff excelarator pedal and I have to excelarate and release in order to change gears.
Once I stop, the engine revs up down and the rpm and oil pressure meters are all over the place as if there's a problem with the throttle actuator but both the actuator and the air sensor are new.
Could there be a voltage problem if the battery under load varies between 13.5 and 14.9 volts.
