Which series (s4-s5)? Turbo or NA? What all did you remove? Why did you remove it? Was your car starting, running, and idling properly prior to removal?

It sounds to me like you have a vacuum leak. Emissions removal should not cause your car to not start. You should still have some vacuum lines, I believe 5 is the fewest you can run, depending on make/model.

5th and 6th port need around 2 or 3 psi to work properly. It was getting the power from your cat but thats only if its a 6 port na 87 or 88. Possibly a few more 13b models fall under the particular criteria.
