Question about 2005 Ford Five Hundred
P2104 - Throttle Actuator Control System - Forced Idle
This code is for a faulty throttle position sensor check to make sure your TB (Throttle Body) is not stuck. 2104 = ECM could also be faulty.
Its possible that you have a bad Throtle Actuator and bad Throtle Pos Sensor (according to the Ford dealer) they need be replaced .

Bad ignition coil,spiking the PCM,spike comes back on TPS Sensor,then to PCM again,putting the car into ETC Failsafe,and you can only go 6 MPH.
If the coils are not the issue,then the 2110 & 2107 come into play, and you spend $700,00 just for a new throttle body. The motor in it is not replaceable as of 2010,may be some day
In that case you better put it on yourself. Only (4) 10mm bolts,but you have to drain a little coolant,as it goes thru the throttle housing

DTC P2104 - Forced Idle Mode
In this mode, the throttle plate is limited to idle speed and limited vehicle speed (about 30mph) only. This can be caused by 2 or more APPS sensor failures or a stuck throttle related DTC.
