As for the original taco doritos, no dear, I'm not the only one who disagrees with you. The ORIGINAL taco doritos did NOT have cheese and sour cream in them, they were added sometime around 1986. Frito Lay even confirmed to me that the ones they brought back are the second phase of taco, not the originals.
Could you do me a favor, can you look at your bag and check your ingredients list and see if it says any kind of cheese and/or sour cream? I'm really wondering if for some reason you've got a flavor that isn't being sold in NJ and that Frito Lay is confused about. That's the only way I know to clear the issue up. If your ingredients list cheese and sour cream, they are absolutely positively 100% without a doubt definitively NOT the "originals".
