Hey I work at a shop in shelburne and I have a 2015 hyundai elantra with an intermittent stall issue. I originally suspected a sticky throttle plate but after removing the throttle body there was very little carbon deposits or buildup in throttle body. Throttle actuation seems perfect. My next thought was ckp sensor dropping out, then I came across your video on YouTube where you had a 2014 elantra with the exact same issue. Problem is that the stall is so intermittent I can't do any real testing, I was wondering if you ever found anything else with that vehicle since then. In your video you scope the ckp sensor and the issue doesn't arise again so you give the customer her car back, I have the vehicle for basically as long as we want it so I want to definitively say it's the crank sensor but I also don't want to just throw a part at it and hope for the best. If you have any info on this let me know, thanks!
May or may not be helpful, I had one Hyndai a few years back that I could never reproduce the stalling complaint.
It ended up having a bad battery terminal. Once I replaced it, the customer never came back for the stalling issue again.
I know it's a shot in the dark.
