Perhaps some add-on engine accessory has been tapped into that line. Does the engine clear up when you put the fuse back?

The instrument cluster connection from fuse #9 passes through (via a 470 ohm resistor) to the red wire on the alternator. Per the alternator wiring diagram that wire is "turn on input - (power up for regulator)”. Is it possible your system voltage is dropping to the point where the PCM, injectors, etc. are affected?
