sounds more like a vacuum leak than a charging issue, if its idling all over the alt is not going to be able to keep up. the engine is not going to die from alt issues

What does the alternator voltage read if someone holds the gas pedal to maintain 1,000 RPM? If it is around 14 volts, the problem is the low idle, not the alternator, and Justin is probably right about the vacuum leak.

ok thats makes sense for it dying .. but if i hold at 1000rpm it does not read over 12.5 on the back of the alternator.. thought voltage reg problem but tried 3 alternators so lost if you use the heat or air on top of headlights car is useless but daytime driving without heat/ headlights is an option if you want to restart it as it dies haha all vac line seem to be connected but not sure if conected proper location...
does anyone have a vacume diagram and i will check all necessary and also whats the fuse box diagram i need to locate the foglight fuse
thank you guys!!!

If your alternator or battery is only showing 12.5 at 1000RPM, either your battery is bad or your alt is bad. But you said you already replaced both of those. What is the condition of the battery cables at both ends? High corrosion can cause issues like this.

thats what i thought.. new battery and 3 alternators less than 2 weeks old that all tested good have been installed bypassed power and ground on alt no luck new terminals just sprayed starting fluid to check for leak in vacuum nothing out of ordinary it does have rough idle tho i have been leaning toward computer replacement but do not know enought bout a bad pcm to rule it out im a bonneville and riviera nut but used to series 2 this my second first gen i have thought about replacing the whole wiring system from the battery to wherever it goes but thats a tall order in the minnesota cold...
