We replaced the alternator/battery 6 months ago.
As it was going bad, the battery, brake, and all door/trunk lights would come on while coasting for a few seconds and stop on start up. As it got worse, the lights stayed on. Well, the lights are back. Only for a few seconds and only on coasting to a stop, usually around the 30 mph. Mark.

I took it to AutoZone and the alternator read 97 vs. The normal 110 I guess. He thought to check the volt. Reg. First. My local guy thought O2 sensor. Any thoughts?

The voltage reg is built into the alternator. So it only does this at low engine rpm's? Or only when slowing down and you get to 30mph? Check your grounds at the body and motor to be sure they are clean and tight first, and that there is no damage to the alt wiring

It doesn't do it on idling at a stand still, only while driving and coasting to a stop sign or red light. All the red lights will come on for a few seconds when I slow down past the 30-20mph. They always come off after a few seconds or when I press on the gas to start again.

Sounds like a charging problem of some kind, might want to try to find a shop that specializes in electrical, they will be able to test the car while driving and check the wiring with a meter to be sure it is ok. Still sounds like a possible bad alt/regulator
