Had to replace another injector today. It was easily detected during the run-up. Engine roughness with Lane A shut down. EGT on CYL #3 dropped significantly. (*No Lane light.  *Apparently a clogged injector won't always throw a Lane Light). Knowing that injectors 5-8 are on Lane B made it easy to diagnose. Injector #7 (3F). Replaced it within about a hour. Problem solved.

FYI: Injectors 1-4 are on Lane A and 5-8 are on Lane B. Watch for an EGT drop and loss of RPM's (>250) during the run-up. I started keeping a couple injectors on-hand and I'm going to start traveling with a pair as well.
