Can a bad ac compressor stop my 1996 buick riviera stop it from starting?

What is your question?

Idle would go high and low. When i stop it would cut off on me. But start back up until it didnt want to start back up for me. Any Ideas for me? I did a full tune up. Change coils, plugs, wirers, oil clean out my throttle body , fuel pump is a month old new fuel filter.. ? What am i missing?.. What seems to make the problem better or worse? When engine get hot How long have you had this problem? Week
