Rover 620 1996 eng code 2TN - Loss of power Archived Message

Reported power loss @1k9revs.
If eng revs held @2k5 & brake pedal applied the engine revs dropped by 200-300..... Ecu codes read & 37 present indicating brake switch error; new switch fitted, rev. drop not now present @ 2k5, code 37 still present.
If revs are held @ 1k9 the engine starts a gentle rolling surge of +/- 40 revs....this has not been affected by the change of brake switch.
My local diesel pump specialist has never encountered this problem. HAVE YOU? Any suggestions would be appreciated.
