hi, I was going to buy a mini with these codes plus random misfire codes as well. My mechanic doesnt seem like he wants to deal with it. I cant find the meaning of P1776 and P1777 codes. Also has a bad misfire (barely runs) and P0300, P0301, P0302, P0303, P0304. (all misfire codes). maybe more too, I didnt scroll down...

Thoughts?

 

I would say you have a fuel pressure problem. Possibly a blocked fuel filter, bad fuel pump or bad fuel pressure regulator. Low fuel pressure is causing your misfires.
