Frölunda started better and also took the lead when Jan Mursak put 1-0 after fine preparation by the back talent Simon Edvinsson.
But before the period was over, Malmö had turned around.
First Carl Söderberg scored his 20th goal of the season and then it only took nine seconds before Christoffer Forsberg scored 2-1.
Just two minutes into the second period, Pontus Westerholm scored 3-1 for Malmö.
After that, Frölunda changed goalkeeper.
Matt Tomkins reluctantly made way for Niklas Rubin on the pitch.
"One of the worst matches of the season"
After that, no more goals were scored and the almost 10,000 spectators had to go home disappointed.
- Fifteen first, I am very happy with.
Then when they make it 1-1, it's like punching a balloon.
After that, we make one of the season's worst matches, says Frölunda coach Roger Rönnberg.
With the victory, which is Skånelaget's third in a row, Malmö is up to the same number of points as Linköping.
Now they have four points down to Djurgården who are in qualifying.
