I have a 1997 Deville with 55k on the clock... I have taken it to 2 Dealerships and a few independent places to get checked... and noone can tell me anything. When it warms up, and I stop at a traffic light it spudders and stalls. Its not throwing any kinds of codes. The dealer has replaced the fuel pump, the ignition, cleaned the injectors... None of this has helped!!!! Please tell me somebody here knows!!

Strange that it is not throwing any codes. Might try cleaning the EGR pintle valve. If it sticks open it will die at idle, but that should set a code. Although the pre 2000's where not known for bad CKP sensors, they will cause the same symptoms and do not always set a code. I hate to suggest throwing parts at it, but that seems to be what you and the dealer are doing and with no DTC's, you might not have any other choice.
