I have a 940 SE and the power stage amplifer (EZ 116) is located on the dirver's side fender located almost directly above the battery terminal. There should be a connector with 5 wires coming out. There is nothing in the TSB on the LH 2.4 EZ116K I have about a Radio suppersion relay.

The power stage closes, breaking the power thruough the ignition coil. When the primary coil current is interrupted a high tension voltage of 30,000 to 35,000 volts is generated in the secondary coil. The high tension voltage is transmitted to the distributor and then to the spark plugs.

If the EZ117K is similar then you might check the ground at the intake manifold.
Hope this helps, let the board know what actually fixed the problem.
