REPLACED INJECTORS, NOW IDLES VERY BAD.

Nissan Pathfinder

My 88 Pathfinder (V6, 4WD, 116,000 miles) recently went into fail safe mode (won't go above 2750 RPMs). The computer code was 51 - bad injectors, although the car idled fine. I cleaned and replaced the injectors, no more error code, no more failsafe mode. However, now the vehicle idles VERY erratically - fluctuating between 1200-1800 RPMs continually. There are no vacuum leaks, fuel pressure is good, ignition timing is good, choke functions. I even switched out computers with no change. What would cause the idle to go so bad immediately after replacing the injectors? I'm baffled.
