94 gt, mods include full exhaust, cobra intake,e303 cam and ported heads, bama chip.

Parts I've replaced ignition control module, distributor (new), cap rotor, plugs, coil, coolant temp sensor, thermostat, maf, put chip on factory tune.

So the car will run fine for maybe a day or just minutes. Ill be going down the highway and ill get a hard misfire. Then its like every cylinder is misfiring, it will run horribly rich, and will kill itself. When I changed plugs after having it towed home every one was black. So i have changed all this stuff and weather i put it on the factory tune or one of the made tunes it ****s up and does this. I just had to have it towed home again tonight. And then it started fine and pulled into my driveway wtf. Im out of ideas besides looking for a vac leak that i doubt is there. This was completely random and happened out of no where. It has been running fine and no had anything done to it in a year. What else can I look for. I had also unpluged the battery thinking it would reset everything when it died on me today, but it didnt it was still misfiring. After changing the maf today i drove it around for about 20 mins in the neiborhood and finally got another miss choke and die out of it. then it drove home fine.

On a side not my battery light is on. Battery is fully charged, and alternator is good putting out 84 amps and said good diodes. The fuse is good as well. WTF do I do now?

I have. is there a setting i can put on a volt meter to check the grounds better? Im not good at electrical stuff. Id figure if the car wasnt grounded good id have a slow crank. Battery is in the trunk with a ground from the post to the body, and 3 block to frame grounds up front.
