so was chatting with a buddy at nissan he ran a test on my battery said, charge it over night... i tried my automatic charger said it was good so it wont charge, so i put the battery back in and i drove the next morning. the car died on me at every light. now i send the car off to body shop for a week, get it back... drive home car dies while driving 4 times, almost got killed having the car die while turning right.. after about 20 minutes the car didnt die anymore.. is this just idle relearn, but why twice a week later after the body shop had it for 7 days. you know they backed it in and out of the shop. i cant think of anything else to cause this no vac leaks that i can find.

 

How old is the battery? What's the voltage gauge showing?

A bad battery can cause all sorts of problems, especially if a shorted cell is pulling the voltage way down.

 

everything reading normal battery is 09/08 titanium autocraft, thinking of going 720 cca red top optima

 

You removed or disconnected the battery? It may take several days for the ECU to "learn" the proper idle.
