A couple of weeks ago i arced my positive terminal of my battery to body...yeah i know it's stupid. Anyways, it was running horribly so i replaced the negative battery cable. It ran perfect for about a day. The next day it started stuttering when i would accelerate from a stop at about every other stop so i replaced the coil. The next day it started doing it at every stop...then the next day it kept was still doing it, but this time it died. I couldn't get it to start for about 15 minutes. I unhooked the + battery cable and hooked it back up, then it started and i was able to get the two blocks to my house. I have no idea what this could be. Any suggestions???

PS i replaced EGR valve, IAC sensor, TPS about a year ago and CTS sensor about a month ago. Plugs and wires are brand new, and the coil and cap and rotor are also about a month old. I took off the performance coil i had on after the incident and put on a stock one to see if it helped, but i didn't really notice any difference until this started happening.
