Changing battery

[rjg1987gn]

I am going to change my battery. Do I need to connect a power source after removing the battery to maintain all codes, etc.. .? My car is all stock eg no chips no nothing .

Thanks
Rick

It really doesn't matter for a stock engine, all you have to do is after you replace the battery, drive the car for about 15 minutes and the ECM will create new inputs.
F.Y.I - you should also have at least a Scanmaster.

Thanks. I am replacing with a NOS ACDelco battery. Now it will be 100% stock. I have yet to buy a Scanmaster simply because the car is running well...and even though 26 years old it only has 39k miles. I know the day will come when I will need one. I have accumulated many spare parts and will need the SM to diagnose which part is malfunctioning.

hello; IMO 100% stock is cool if your going for points in show but if it was me I'd get a bat. with both side and top terminals.
If you ever had to jump off those side posts you'll know why.

i'd be more worried about having to reset the clock and all your presets on the radio than erasing the computer memory..
