Not sure how close you are to Marc Haibecks shop but you have to be closer than I am. I spent 2 years tinkering over similiar "nagging" type problems. I finally decided to hire an expert.

I'd drive the car over to Marc's and get his opinion. He's great about offering useful advice, even if you are determined to fix it yourself.

Changing one injector is do-able but I'm not sure I would take that approach. If the injectors are new, it's not out of the question but highly unlikely that one is bad. Perhaps someone smarter than I can offer an opinion on this.

Visually, there is a clear difference between Lucas injectors and the OE versions. I still have my (bad) OE injectors. I'd be happy to give you one for comparison. Since it's winter and if you don't use the car as a DD, you might consider removing the plenum (Marc sells a detailed DVD on the how too's) and see if your injectors are OE. If they are, I picked up a set of Accel injectors from Marc and had them in 2 days (he keeps several sets in stock). I got some expert help for Aurora40 and they were changed out in a day. If they are OE, I'd highly recommend changing them out. After tearing apart an OE injector, there is clearly a metallurgic incompatibility condition taking place. I don't know the cause but I'm working on it.

The only problem I found is while my car only has 10K miles it still is 16 years old. I had two vacuum leaks I just could not find. It took Marc about an hour.
