Battery Question
My 1995 Base Coupe has been out of service in a warm inside garage since November due to an injury that I had.
At that time, I disconnected the battery because I knew I wouldn't be driving until spring. Is it bad to leave it disconnected? Will any stored info disappear from the ECM?

You won't lose any important info. At worst, you'll start off with the default parameters until it relearns itself.
You will lose your last MPG or Trip meter numbers. And, all of your radio presets are surely whammo - 87.5Mhz!

Acually it better to leave it disconnected if not on a trickle charger to avoid any parasitic drains

@pltmgr Thanks. I'm actually a bit nervous about leaving it on a trickle charger plugged it all the time unattended. New battery, so I've sure that it will hold a good charge until I connect it.

Living up there in the cold winter, don't be surprised if your battery is dead but being inside a garage may have saved it. Put it on the charger for a few days before you totally drain it trying to start it.
Most of these cars will start at 10.5 - 11.0 V but yours is probably low sitting for three months.

Today trickle chargers are "smart" and will not overcharge/hurt your battery. I leave my non daily drivers on chargers 100% of the time and get 10-12 years from Walmart batteries.
