Rough idle when on a downward sope
I don't drive my car everyday and last week I drove it and someone cut me off in a parking lot and I slammed on the brakes and almost stalled it out. it didn't stall but right after that I stopped at a light that was on a downward slope and it started idling rough and wanting to cut out. I drove it home and it ran fine but today I started it up after it was sitting facing downhill in my driveway and it ran rough and was blowing black smoke when I gave it gas. It drives fine and no issues with boost any ideas?
No CEL's or anything like that, possible evap purge solenoid clogged?

EVAP Purge issue or the start of something with the low pressure fuel pump in the tank, it bears keeping an eye on. Eventually it'll pop a CEL if the problem occurs during enough run cycles, but you can always swing by an auto parts store to have the codes pulled because it might have already set one.
