Happy New Year, everyone!

My 2014 Infiniti QX 80 started having engine shaking 2 weeks ago while the "check engine" started blinking. Since about 3 months ago, I can hear water bubbling noise from dash area, most of the time at a traffic light when the vehicle was stopped or slowly moving.

I brought the car to dealer, report said "high pressure fuel bucket has collapsed" and recommended "high pressure fuel pump replacement along with timing cover and lifer bucket". They gave me some pictures but I don't know how to upload them from my PC. Leave me an email if you would like to see these pics.

I also used a self-diagnosis device to check the vehicle. Codes popped out: P0300/P0302 and P0021.

Anyone has experience on this issue? Recommendations are greatly appreciated.
