Mustanguy

It's not any different,I and many others who own mustangs with 5.0 motors all have the same throttle bodies up to the year 93'
You have the same TPS sensor,You have the same throttle spring,throttle blade,Idle Air Bypass.They all have the same externals for setting the idle.

The mass air meter of a car does not have anything to do with setting a car's idle,it measures the air going into the motor and the computer adjusts the timing and fuel requirements for best performance,it has nothing to do with the settle the idle.Why do you think speed density cars idle WITHOUT a mass-air meter? Because the mass-air meter is NOT NEEDED to have a car idle,therefore you dont need to have 2 different procedures in order to adjust the idle on a mass-air car and speed density car. It's all done AT THE throttle body.

Case in point,here's a article that talks about adjusting the idle on the years of 86' to 93,nowhere again does it say it wont work with speed density because guess what it does

Ford did not switch to mass-air til 89 so this covers the years WITH speed density when setting the idle

Another source again with no mention of only working with mass-air

Like I said before,this method works for both speed density and mass-air and to call 82'GT's experience a fluke is funny as hell, because people use the same method for setting the idle on speed density and mass-air equipped cars.

If you doubt me so much,post on some other forums, you will have people adjusting their idle the same way whether it has mass-air or speed density,because having or not have a mass-air meter makes no difference when adjusting the idle.
