Saturday afternoon, I had to replace the battery in my '92 bird(V6) because it was shot. It was a cold day and the car wouldn't start even after I tried to jump it. Needless to say, I took the battery out and put in a brand new Delco battery from my GTA (stored for winter). The car starts up fine now, but when I come to a stop, The RPMs drop low to about 500, bounce up and down(rev) a little and sometimes it stalls. If I shift it into neutral it revs up then it's okay. I have owned the car since November, and it's never done this before. I guess my question is, could it be that the battery is causing the car to stall out like this?


Thanks guys.

 

If the car is an auto, check to make sure the TC is unlocking properly.

 

The only thing is though, the car never did this until I replaced the battery. Is it possible it could be the battery?

 

I don't see a battery causing only a problem in gear and not neutral. Try coming to a stop in D not OD and see if it still does it.
