Peugeot 406 cutting out

Car: Peugeot 406
Variant: 2.0 16v Auto
Model Year: 1997
Categories: Running Rough, Starting & Power Loss
My 406 cuts out when engine is warm at steady speed or traffic lights.It has a rough idle and revs seem to pulse.Been in garage and no faults are found on the ecu.Had stepper motor changed but this has not worked,this unit was second hand so could be faulty.Could the problem be the Throttle Body? Fault is driving me mad as car cuts out constantly making all journeys over 10 miles impossible.Thanks

second hand parts are risky thing when dealing electrically but clean out the throttle body and see how you go from there if problem persists then get hold of a new valve
