I’m new to working on cars, this is a two part question..1: in the picture I’ve added what is this?
https://www.dropbox.com/s/8noq1pg1oodqyaz/IMG_20221031_150748852.jpg?dl=02: I have a 2016 kia Forte koup sx t-dgi and the needle is jumping at idle and the car is chugging. It was caused by a racechip I bought, I guess the stress and a lack of upkeep on the vehicle caused it to end up throwing me an engine light and codes to do with injectors and coils.turns out the plugs where destroyed, the injectors looked like crap and the ignition coils needed replacing. It probably hadn’t been taken care of or had any of these things replaced and it’s a 2016 with 80000km
I’ve changed the spark plugs ignition coils and,injectors..in that exact order, cleaned the throttle body, now correct me if I’m wrong but all I have left is the fuel filter and the fuel pump, correct? Or am I missing something?

Unable to view the image, sorry. That said, modifying vehicle systems doesn’t always work out. In fact, it rarely does. I recommend putting everything back to stock. As for the performance issue, you might find this info helpful: http://www.ericthecarguy.com/faq/solving-automotive-performance-issues
Good hunting.
