Glad you found it!
<<< hates electrical gremlins.
I knew I had a misfire from 4000-5000 rpms and had a full set of coil packs laying around so last week I finally pulled off the old set and found the rear most coil pack torn and surrounded by filth compared to the others. These look to be 158k original coil packs, the cylinder numbers are in order and still visible.
I can now feel the car pulling harder and running correctly on all 5 cly, but now there is a boost leak at the same 4000-5000 rpm which I have been looking for but have had no luck finding yet. My next issue is with the + battery cable/terminal, it needs to be replaced due to someone using a non-vented battery at some point in its life according to my quattroworld search. I just cant seem to find a 1 guage butt connector for it, does anyone know a local spot i can pick this up? I bought a nice fresh non corroded California cable
Also next on the list is the sunroof which doesn’t receive power at all, the fuse is good, the relay is questionable, is there any other buried electrical component that should be checked off the top of anyone’s head? I haven’t looked into it too deeply yet
