Help with running problem!!

[04owmach]

haha well so far i still have just a few dollars over 2000 in this thing so im not gonna complain... picked up a computer today and yet again it runs better but not fixed... starting to think about weak coil maybe... i can straight up put my hand directly on the wire and not get shocked at all and it has an msd blaster coil on it... ive always heard that if you touch those things they will knock you on your ass... just a thought

if the wire is hooked up it will not shock you but if you try yanking it off while the car is running you will see the light, try doing the koeo koer tests and see what codes you pull up this could be something complety unrelated to everything else
