Scotty. hoping you can lead me In the right direction. I have a 2019 Ecoboost mustang with 36000 miles on it I was backed into at the store and the active shutters took a little damage but we're still working okay. now 6 months later I am getting a service engine light. I checked it with forscan and it threw the code for the shutters not working correctly. I did remove them. but before I did I started to get cylinder temperature warnings even though they are gauged and staying right at 185-205 degrees. also. now my water temperature gauge will all of a sudden peg and I get a coolant temperature alarm too. when I pull over it is evident the car is not overheated by any means. I removed the shutters from the grill and that code has gone away. this evening I am cleaning the maf sensor and throttle body out as I write this. because I did read these turbo cars have quite a carbon buildup issue. is there anything I should also be checking out? please advise as of course I am 89 miles out on my warranty. I am also getting a #1 cylinder misfire and when you first start it it idles rough until you press the gas one time. Then it smooths right out. This all happened in a week's time.
Thanks.
Here are the readouts from forscan. I dont see anywhere to upload or I would show you the graphs as well as the oscilloscope.

Well once you hit that front all kinds of wiring damage could have a card feeding back into the systems doing all kinds of squirrely things. Obviously it wasn't overheating if the temperature gauge was normal. I pray it some type of wiring sensor damage because there are so many things that can trip those codes make your head spin if you have to start from scratch. But swapped ignition coils and if they miss moves pray it's just a bad ignition coil this may get misfire
Could be any number of electrical wires damaged after the impact.up front.
I'd start looking for a good Mechanic to look it over and locate the issue.
I've actually had it apart to take the louvers out. The car was just barely backed into from a parking spot. Didn't even crack the grill. And that was way back in January. I noticed I put a gallon of water in it. Was driving okay. No miss. Then the battery started acting drained. I checked it and it checked 11.92. Way low. So I took it to a different dealer. Remember the first one said there was nothing wrong with it. Even though Forscan was throwing several codes already. I pull into this dealer. It's idlung just fine. Give them the keys. They pull it around to service shut it off and that's the last time it started. Locked. Up. I'm going to say it's hydro locked on the first cylinder. Why? Because the first cylinder filled with the missing water from a broken head gasket cylinder side. That had it for 2 weeks without a call. So I called and they confirmed. Head gasket and cracked cylinder. Which he told me has been a major problem with that year. That being said. They ordered me a brand new engine. Ford performance is installing and it's on their $ no questions even asked. I told them I had a few factory approved parts to put in it and I wanted it retuned like it was. Ford stage 1. They said drop the parts off and if they are ford approved they wrote the install up with the warranty. That's pretty damn cool. They also said. The other dealership should had never let me drive away. It will be 3 to 4 weeks to get it back. My next question would be is going to be ok with that transmission? Do they reset programming so it will relearn together. I'm not sure. Should I just trade it in when I get it back?
