ECM newbie

Hello all,

I have a high mile 88 gta with intermittent problems here and there. I am trying to get a deeper look into the engine before I just go replacing things here and there. I have Tunerpro rut and all the cables and such and I can pull numbers off the ecm now but I don’t know what I have when I do. So I am hoping there is a resource somewhere out there that one of you fine folks can point me to about what the things I am seeing mean. I don’t know if my numbers are in a good range or not so.... Like I said I am starting out from full ignorance here. Any resources you could point me at would be greatly appreciated!

thanks
