Adam Lowry had a goal and an assist, and Connor Hellebuyck made 40 saves for the Jets (4-3-0), who opened a three-game road trip. Winnipeg plays at the Arizona Coyotes on Friday in the second game of a back to back.
"I know it's not VHS tape, but it's in the garbage," Jets associate coach Scott Arniel said. "We won't even [look at it], we'll just put that one aside. … There's a lot of mistakes that happened, but there's a lot of good things also. We found a way, and you can never criticize a win."
Trevor Moore had a goal and an assist, Jonathan Quick allowed five goals on 18 shots for the Kings (4-5-0), who have allowed at least four goals in seven of nine games this season (2-5-0).
"We still don't know how we want to play," Los Angeles coach Todd McLellan said. "I would think the experiment of run and gun that we are trying to play, how much more evidence do we need that it doesn't work?"
Jonsson-Fjallby redirected Brenden Dillon's shot from the blue line, which sent the puck to the far post when Quick had already committed at the near post to make it 5-4 at 14:23 of the third.
