96TT MAS question

I need to go back to Autozone and get the code, but remember it was the MAS. I installed my old MAS from my 93TT and the CEL stayed on. Figured it was because I had removed the honeycomb out of the 93 MAS as I was running speed density at the time and wanted to open it up a little. The thing is, regardless of the honeycomb removed or not, once I hooked up the 93TT MAS and went to ACC the CEL should have went away correct? I would understand it coming back once I cranked the engine. That is assuming years of sitting in my shed didn't cause it to go bad. Guess I could have them read the 96 MAS then reset and hook up the 93 MAS and see if the same code comes back.
