this just recently happened to my bird. Sometimes when i go to start it, it seems like the engines not getting any spark, and it just keeps tryin to turn over, very slowly. But if i wait a few seconds and try again it will fire up, but hardly, it idles hard and loud, sort of like when a cylinder won't fire, sounds like crap at a stop too. i didnt know where to post this, i think it could be something electrical? ignition coil? someone help please. i also went to start it last nite, and smoke poured out from under the hood, i took a look under there and my negative battery cable was smoking and melting? can anyone tell me whats wrong?
