Injector replacement input needed
2018 GTR with 6K miles was running rough, took it into dealership. Swapped out 4 spark plugs on one side as it had multiple cylinder misfires on that side. Still had an issue after hard acceleration with it stalling and going into limp mode so took it back in. They said I now only have issue on #8 cylinder. Dealership just called and said they had been working with AMG engineers and they want to replace all 8 injectors for $10K yet only one cylinder is having an issue. Would love your thoughts on why they can't replace just one and should I go through with this?

changing all 8 injectors might make sense if the car was still under warranty but doing that out of warranty at a cost of 10k $ is crazy.... just order to replace that injectors and see if the problem is solved....

If all Yes, do a search on this form on similar misfire issue. I recall from the far past that someone had a similar issue it end up being a loose ground wire.
I hope it is one of the above
Good luck
