I live in ohio. its been 80% humidity. I also lived in Texas and Okla where I never owned a house or car that even had AC. Going to be 85* here again for the 4th day. I didnt even break a sweat working in the garage. Even had the door closed while painting.

Mythbusters didnt do a complete test on that. They had a normal size vehicle and were checking to see if you got better mileage with windows open, or windows closed and AC. Not much difference there. Now if they tested something like a 2 ltr Cavalier, the air compressor drags down a lot of hp. and that might change. My 2.7 Sebring on the freeway can feel it slow down when I do kick on the AC compressor. When you only have 150 hp, taking 25 to run the compressor is quite a drag. On a 350 v8, theres no effect.

Getting on the freeway and comparing it to a run down the drag strip, Ill bet the AC compressor on alone adds a few seconds to the ET.

But you are forgetting that the widows down can cause drag, which also takes power to over come.

So no matter which engine you have, you need to see which uses more power, the compressor or the extra drag.

Do some searching. You are an intelligent human being. There is a lot of information on the net, and for a/c basics, it doesn't need to be Fiero specific.

Here is a quick link I found that might be helpful.

My Fiero needs a new pressure switch on the compressor, and it will work(leaks). Problem being that is a royal PITA to work on under there and I am not looking forward to it.

my 2002 s-10 4 cyl 5 spd really has not affect wheather the AC is on or not on the highway. Stop and go or city might make it go down a few, it's gutless with it on.

Yes thats what they proved. But again same thing applies, open windows do cause drag, but bigger engines deal with that better, same as AC compressor. My Sebring loses about 1.5 mpg with AC on. Without the AC, putting the top down dont have any effect....mine does have the instant MPG readout. With the Coronet, I have same power with or without windows down (413 V8)
