Titles mostly says it. I have a 2012 Malibu that after driving for roughly 15-20 minutes will try its best to stall out when moving slow or coming to a stop. I can see the RPM meter jumping up and down. While idling in drive or in park, it also tends to stall. It also sounds incredibly loud while idling, and you hear the engine, almost like, revving some. I was thinking either, a catalytic converter issue or a fuel pump issue.
