Got to the g/f's place Friday night and was running fine. Went to drive her out to deliver a cake on Saturday morning and had a dead miss. Since the cake and work were close by I stopped up at work and found the issue.

I started by pulling the injector connectors one at a time to find which cylinder had the miss. The winner here was #3. Pulled a spark plug boot with it running and it had decent spark. Plus I wasn't getting fuel or backfires from the exhaust. Figured I had an injector issue. Measured resistance on 3 and found:

Measure #2 and found

Called up the local parts source and they had one in stock for $100. They said it would be around 2.5 hours before they could get it to me b/c it came from their warehouse. Killed some time and got the call to pick up g/f. I had my brothers R32 sitting at work waiting on some parts so I took it to pick up the g/f from cake party. Got back and the part showed up after 2 min of b/s with service writer. Popped her in and runs like a champ!
