The idle on my 94 accord drops low as if it is about to shut off when the fan comes on. and sometimes when I use the power windows, the idle will drop as well, it corrects it self, but it goes to low.

 

I think thats pretty normal mine does that all the time, its just cause your draining more power. How low does it drop?

 

the lowest mine ever drops on a 94 is just slightly under 500 mark... hmm tried cleaning out your grounds? not sure if itll do much, but worth a shot :\

I'm not sure, but I think it could be an early sign that the alternator is going bad. My car used to do the same. Once I installed a 140 amp alternator, my idle never dropped or dimmed the lights, when I used the A/C, defrost, rolled down the windows, etc.
