Trouble Codes Solutions

I am looking for a download or a link where I can find solutions to trouble codes for a 92 Taurus. I ran the self test and pulled a few codes. I know the description but i dont know the fix for them. The codes I have are...

157 Mass Air Flow signals/was low or gounded
158 MAF sensor is/was high or short to power
327 EGR feedback signal is/was low

and a bunch of tranny codes...

621, 622, 624, 636, 637, 639, 641, 652

thanks.
