My yellow ECS (emission control system) dashboard warning light went on for like a day last week...I had my friend read the fault codes (see below). Are these issues ones that I should take care of sooner vs. later or are they something to just keep an eye on?

The ECS light went on again (and is currently staying on).

Bummer. It looks like you'll need a new engine mount. There's a switch in there (not a solenoid) that trips (goes open circuit) to let you know there's a problem. It tripped 7 times so it's probably not going to fix itself.

The misfires only happened once (Frequency 1) so I wouldn't worry too much about it just yet. If it happens much more, it needs to be addressed. Some things that could cause misfires are bad gas, not having the coil recall performed, carbon buildup, or just needs a fresh tuneup (spark plugs and air filter).

Good luck, let us know how you make out.
