Hi, The P0300 code is described as a random misfire, with numerous potential causes. Have a look at this website engine-codes for more information. I'm sure that if the fault was an ECU issue then the doctor could cure it, but from your description it is not at all clear that this is the case. But from the description you can see why the garage has done the actions it has so far. As the above web page shows there are many causes and lots of easier things to try before sending your ECU for repair. Good luck with tracking this down.
