You guys can see what I have from my sig and I pass just fine (better than my wife's V6 Prope). I have no idea why bada$$lx would fail with e-303.
Back to mustangLX92's problem. Forget pulling an injector. Just go take the test and see if you pass or fail. It's not like they'll wisk you off to jail or something if you fail. Just make sure you're running with 10 degrees timing and 87 octane. I hope you have cats and a working air pump, too.
If you do fail, you're in a better position as to what to do about it.
