P0300? Check for vacuum leaks.
Just an FYI, I had my car running kind of garbage for the past couple of years, a thorough tune up would get it running better, but not how it was pre-Head Gasket replacement.
Long story short, there was a small leak around fuel injector #1, which got worse over time. Late last week it stalled for the first time ever (under hard deceleration to a stop), and it was really terrible.
New O-rings on all the injectors, and the car is back in business.
It had P0300, P0301, P0302, P0303, P0304... hopefully this will help someone if you run out of ideas. I cleaned and replaced damn near everything at one point, even swapped parts from a donor civic to eliminate possibilities (throttle body, fuel pump, ignition coils, etc) and was unable to pinpoint the issue.

If you think a good mechanic is expensive, try hiring a bad one

New O-rings on all the injectors,
How did you diagnose this? Did you hear the leak, did you spray with carb cleaner to find it?
