Review on 04891735AC - ChrysLer Electronic-Compatible Ler Replacement by Osoulo Sharp

I bought this a while ago and it worked great. It's been a few months and I'm having the same issues as before replacing the part. I can drive in the middle of a freeway and then my car starts jerking and my speed slows down. The seller does not give me his data. I googled them and it shows another location and they said they are not connected to them and they get calls all the time. Raven won't help. I have been told that I have a two year warranty on this part and that I am still under warranty and there is no way for me to contact these people.
