Hello. My name is ***** ***** I will be assisting you today. This sounds like you have burned out the pcm. This reversal of power will cause much harm, depending on how long the battery was connected. Usually once this happen, circuits start shorting out and even melting may occur. How long was the battery connected?

Do you have a check engine light on?

Customer: replied 1 month ago.
No engine light on and at the time only for a few seconds which was a couple months ago and now when I drive it it sounds like it wants to dye and sometimes I will loose all power and sometimes it will drive fine for a few days

I would check all connections, for any burn signs. Especially near the pcm(I would actually have it checked), ignition control module, and fuse box. You may have to take it to a shop that has an oscilloscope so that they can monitor the system and truly see what's going on.
