Po300 random mulitple misfire detected p1399
If only one of your cylinders was misfiring, you probably would be getting a more specific code than P1399.
Also check the distributor rotor along with the cap and coils and wires (as mrgreenz suggests); the EGR valve to make sure it doesn't leak; your fuel pressure which can cause random misfires if the pressure is too low; and injectors if they are really dirty. If you have really high mileage, I probably would first just change out the plug wires with a new set, then reset the DTC and see if the code comes back.
Hope this is helpful as well.

Maintenance Light goes on/off/on
When your vehicle is coming up for due maintenance, the light will flash for a few when you start the car. When the time for scheduled maintenance is due, the light will remain on constantly. It's just routine maintenance, but if you haven't done it, that's your reminder. Then, you or your mechanic will have to reset that maintenance reminder light.

First check the connector and wiring. If good, remove the idle air control valve and clean the passages as well as the valve and seat. Reconnect the valve but don't install. Have someone start the car while you plug the downstream passage. The car sould idle down or stall, and the valve should retract. Remove your finger, and the valve should extend. If the car will not idle down with the passage plugged, you have a vacuum leak. If the valvedoes not react properly, check continuity of the wires to the ecu.
