Hey all, so I've been having this issue recently with my 2007 Acura TL and I'm hoping someone can point me in the right direction to get this issue resolved. So, this issue started this past weekend. I got into my car Saturday morning to drive home and about 10 minutes into my drive, the car starts sputtering and shaking really bad and my CEL comes on flashing. The dash notification says "Check Starting System" followed by a burning smell from the vents, then all of a sudden the screen starts throwing all these codes out. I dont remember all of them but the ones I do remember are U0107 & P0304. So I continued driving it until I could get to an auto store and upon researching the codes I figured maybe one of my coils/spark plugs just went bad and needed to be replaced. I bought a new coil and spark plug to see if that would fix it. When I went to pull coil #4 the head part completely detached from the tube and the remainder of the coil pack was melted solid in the cylinder. I managed to scrape it all out after about 7-8 grueling hours of hammering, scraping, and drilling. I put the new spark plug and ignition coil in but the car wouldnt start until messing with a 15a fuse. I drove it home, but it was still shaking really bad and 2 days later when I went to check the coil, it had yet again melted inside the cylinder. I read in the forums here that it could possibly be an issue with the ECU being water damaged. So I took it out yesterday and did observe some stains on the top of it but no evidence of water or moisture anywhere so I have no idea how it could've gotten water damaged. I'm at a loss. How do I know for sure that the ECU is damaged and how do I go about finding the source of the leak/drip? I ran the A/C for 10 minutes and did not observe any leaking. I've attached photos below, any help would be greatly appreciated!
