engine & "slip" light weird

[matthewai]

so today i was driving normally like every other day and these 2 dash lights came on for no apparent reason. (check engine and the "slip" *not the traction) i did nothing went about my business they stayed on after 2 stops and starts, then i drove to brooklyn was there for a few hours got back in to leave and they never came back on. any opinions or info ? pretty weird only thing i could think of that might have caused it, i was running the ac before they came on for longer than i usually do (was on the phone with mi in the car while it was running getting something sorted out and ordering the ecometer) but i dont see why that would be a cause
