SOURCE: car runs rough at idle
clean out ur throttle body, just follow the hose from the air filter to the throttle body. Need 2 people to do this. Don't remove the hose completely from the throttle body. Just enuff to be able to spray ur intake cleaner into the throttle body. Do this especially if its worse when the motor is hot, as this would confirm the problem.

Wow you change everything, TPS was right thing to do and so is the Idle air control,and MAF and EGR, fuel pressure, So it idles high then some one tried to defeat the stall in gear? Even if there is a vacuum leak creating high idle it shouldnt stall in gear, , What color is the transmission fluid? when in gear in drive step on the acelerator pedal to maintain idle to prevent car from stalling. Just enough to maintain let say 1100RPM. Is there a vibration? I mean a torque convertor vibration. Torque convertor stall are common an GM and Nissan,very rare do I ever see it on Ford. I really belive the IAC is not getting power and is just been adjusted manually, cause I know its not the transmission, At idle in gear pull the plug on the idle Air control does it change in idle setting? If it doesnt change in Idle setting the adjustment that was use to control the setting lower the idle to its normal setting. Plug the idle air control in then.The idle air should change the setting. If it doesnt its not getting the signal it should.

Remove the mass air flow,and clean it with intake cleaner spray,or mass air flow cleaner spray,if this does not help,reset the system again,by removing the negative battery cable for at least 20 seconds,then put it back on,if this does not help,replace the mass air flow sensor
