Took mine in Monday and picked it up Tuesday. Car drivers a little better now, it didn't actually ever stall but did stumble sometimes while idling or pulling up to a stop sign/light. I've had no issues otherwise.
Got mine done 2 weeks ago. If you would start it with the A/C on the RPMs would drop below 500rpm and the car would stumble/shake until the idle came back up maybe 1-2 seconds later.
After the fix it still does this, maybe a quarter as often. No biggie.
