My legacy has lights coming on. Brake light is flashing, check engine light is on, cruise light is flashing
Check your alternator to see if it is charging.
This may sound wierd but it may be your gas cap is not tight. I had something similar, don't recall all the lights that flashed but recall it was more than one. I tightened the gas cap and the lights quit flashing about 10 miles or so later.
I have the same problem,I used my scanner to clear the computer and it runs for two weeks then it came back,scan it again and it said need a Map Sensor with the code a little piece of plastic cost $200,plus labor ,Manifold Absolute Pressure Sensor
