1988 Chrysler Lebaron Stalls at Idle Sign In

1988 Chrysler Lebaron
2.5L 4 cyl.
Automatic Trans.

Hi. Well my mechanic said this was the only car in 20 years he could not repair.
I'm hoping it's something so simple that he is just overlooking the problem.
The car started rough idle at red lights or in traffic and progressively got worse.
It now will not stay started, unless you keep the engine revved.
Some thing strange he found while working on the car was that if you disconnect the
alternator from the battery the car will run smooth at idle. As soon as you plug in the
alternator the car will kill. Alternator was changed and did not fix the problem.
With the car running at about 1500rpm and the alternator plugged in, I checked the voltage on
the battery and it is 13.7 volts. It seems the charging circuit is working properly, right?
With the car running on just the battery the voltage is 12.3 volts.
Why would plugging in the alternator kill the car? He also changed the computer just
as a last resort and it still did not correct the problem. Any ideas? Thanks in advance.
