Coil issues code P0302

[Sambodean]

7544875449This issues is with an early 1999 a4 quattro with the 1.8t. I’m fairly knowledgeable in the mechanical aspect. The car started running rough (missfiriing) after a FMic install. It was throwing code p0302. I swapped a known to be good coil with the “problematic one, and the issue didn’t follow, but stayed with cyl 2. Now I know it’s not the actual coil, I’ve already installed new plugs, checked the beginning of the coil connection and there seems to be no ferrying or exposed or melted wires. I was just going to replace the harness, but I can’t find any after market replacements for my coils! My coil slots have 3 prongs, all the others I’ve seen have 4 for a different model year.

Any ideas or help to rectify this issue and I’ll be truly greatfull.

I’d be happy to help with the harness, if you post here/send me the VIN I’ll send you the OE number.
However before changing it, it seems like you’re guessing that this is the issue, or are you sure? Are you sure the compression/leak down, injector of cyl 2 are all ok? (I assume you tested with the new plugs and the code is still there)

Looks like its a better version of an ECU, with older turbo, and 2.0 or 1.8t, but no, because, it aint that....
