If the Power train control light is flashing then she needs to get to a good local Ford repair shop or dealer
to have the car hooked up to a diagnostic scan tool and check for malfunction codes .
If she is not experiencing any engine misfiring then she is okay to keep driving until she can get to a repair shop.
If she has the automatic trans then she maybe having a problem with this , The PCL warning light is a none emission type code.
So after doing the diagnostic scan she will then know what her problem is .
If she can get the malfunction codes and want confirmation of this issue then please post the codes here for me to have checked .
