Car keeps misfiring

I keep having this issue where my engine keeps blowing coil packs and misfiring.

It'll start off really slowly and gradually gets worse until the whole car shakes. I need help finding the source of the issue, I have gone to many mechanics already and they just keep changing coil packs as if its normal instead of getting to the root of the issue.

Any one here have any ideas on what it could be, I would really appreciate any help and ideas that can help me get rid of the issue. If I cant sort this out I will have to be getting rid of the problem and I really don't want to do that cause I love the car so much!!

Thanks. Codes dont appear on my obd2 and they look burned at the tip sometimes. But i dont believe they have been tested.
