1991 Buick Century 6 cyl Front Wheel Drive

car stalls while driving and even when stopped at stop signs and red lights. The plugs have been changed, air cleaner, fuel filter, throttle body was cleaned and top of the line fuel injector cleaner was added to no prevail. I have heard possibly coil packs, fuel pump. I am trying to save money on this otherwise fine running car, and would like to try and fix this myself if possible. I would greatly appreciate your help in trying to help me. Thank you and have a great day.

You should be able to check for applicable mil codes, if there are any? I'd use a fuel pressure gage on it. Some of the national brand autostores used to loan out a fuel pressure gage, if you don't have one.

Take the throttle-body off and clean it, all passages and throttle bore. Check the iac and tps. I wouldn't replace anything without something pointing me in a particular direction.
