2007 Lincoln MKZ Same Issue as last post

Hello! I recently posted about my car, and to preface again, I do not know much about cars or mechanical repairs. The issue before was that the check engine light was flashing and was jerky when coming to idle and when coming to reverse. This was maybe a month ago at most. I got it fixed and I felt the car ran smoother overall and did not have any more issues. As of just right now, the same thing started happening, only now I can feel it jerking more when it’s in drive. I attached a picture of the repairs made from the first go around. Any thoughts or ideas or what could be wrong? I don’t wanna put so much money into 10+ year old car. Thanks!
