MMC i would wait and see if the situation clears by itself, and good you found the eliminator was disconnected.

If it does not reset itself you can try to clear the faultcode which is stored inside the ecu's memory;

And a description of some code indicators copied from one of my docs on cb1100 files.

Actual system codes are more involved than just a one or two digit code. For example, code '8' indicates a throttle position sensor (TPS) problem but code "8-1" and "8-2" provide more information as to what's wrong with the TPS. These more complex codes can be read by specialized equipment (e.g. an MCS scanner).

When all codes have been observed (i.e. the sequence has repeated a couple of times) and you've noted all the code(s) present, turn off the ignition.

You can now remove the jumper, replace the cover cap on the DLC and re-install the seats.

PCM codes and their meaning
PCM DTCs:

1 - manifold absolute pressure (MAP) sensor (1-1=low voltage, 1-2=high voltage)
7 - engine coolant temperature (ECT) sensor (7-1=low voltage, 7-2=high voltage)
8 - throttle position (TP) sensor (8-1=low voltage, 8-2=high voltage)
9 - intake air temperature (IAT) sensor (9-1=low voltage, 9-2=high voltage)
11 - vehicle speed (VS) sensor (11-1=VS malfunction, intermittent connection etc)
12 - #1 (left) fuel injector (12-1=FI malfunction, intermittent connection etc)
13 - #2 (right) fuel injector (13-1=FI malfunction, intermittent connection etc)
21 - oxygen (O2) sensor (21-1=O2S malfunction, intermittent connection etc)
23 - oxygen (O2) heater (23-1=O2 heater malfunction, intermittent connection etc)
29 - IACV (idle air control valve (29-1=IACV malfunction, intermittent connection etc)
54 - BA (bank angle) sensor (54-1=low voltage, 54-2=high voltage)
86 - serial communications (PCM to cluster) (86-1=communications error, bad power to cluster)

Not saying this will stop the uptick of the rev's but worth a try.
