No, Idle Actuator reset needs a diagnostic system like FiatEcuScan or AlfaDiag ... throttle reset is where you turn on ignition for 90 secs, then off, then leave to idle for a few minutes but you must NOT touch the throttle.
ECU reset is where you clear the stored parameters so it can relearn. People say you can do that by disconnecting the battery ... only do that if you have your radio code. But I prefer to clear this using my FES/AlfaDiag software.
You don't say much about which 156 you have ... engine size, age, manual/selespeed, etc. That might help us help you.
Although you did say that you cleaned the throttle ... that might have been your first mistake, especially as you will have moved the throttle butterfly flap which may have knocked the idle actuator out of sync ....
But newer cars, and V6 and selespeed, have an electronic throttle and that brings a whole new bunch of problems ....
