Hello everyone I’m looking for any help or suggestions. I got this car awhile ago and it has had a stumbling issue since about the 3rd day after I started driving it. It’s usually after the car has been sitting then about 1-10 mins into your drive it cuts out usually when your just accelerating a touch. If you try and keep accelerating it becomes very violent cutting in and out. If you just coast to the shoulder and either wait a few secs or turn off then back on it’s fine for as long as you drive it after. Then if car sits a few hours it will do it all over again. Things I’ve tried are camshaft sensor, cleaned and tested maf sensor, fuel filter, timing belt,dielectric greased all sensors that I could,inspected air box,had it deleted and tuned. I think that’s about it, the car runs absolutely perfect other than this issue and I love it but it’s dangerous and embarrassing the way it is. To me it feels like it’s sucking in a few drops of water or at least that’s the feeling. Please help Thanks.

I was having the same issues on my 2013 Jetta Sportwagon, I change all injectors and it keeps doing it, recently I remove the glow plugs and it was some type of rust, with a sand paper I cleaned all and after that is been running smooth.
