I got "lucky" because they don't carry my white interior anymore (it was known issue how crapola it was). They had no choice but to replace all of it.
Here is a quick before and after, we decided to ditch the main white all together and go with honey diamond.
Just a heads up, you need to turn the key to the on position and wait for 5-10 seconds for the system to zero out and gauges do their sweep. Maybe you already do this. But this is a pretty common thing for tabs to not work correctly. Especially since you say you have to "reset" it on the trailer.
I the engine isn't misfiring I wouldn't be too concerned. Its likely from excessive water getting in the engine bay. Sucks they got you for 3000. your probably 1000 or less just in parts. And them coils were probably just fine. Maybe keep the old ones incase you run into an issue on the water.
