ok so i get this strange humming noise.. it comes and goes as it pleases i can find any cinsistency in when it starts and stops.. sometimes it goes away if punch the gas real hard... and some times it goes away when i let off the gas.. and some times it wont go away .... any one had this problem before?? it sounds like its comming from the engine but im really not sure...

ok as for the misfire.. i know its a misfire and im pretty sure it because my spark plug wires are arking across the block.. ive replaced the plugs and wires about 3 times and each time ill go away and come back.... and its not always misfiring, some times it does and sometimes it doesnt... has any one ever had that happen before, and what do yall suggest i do.. i tried to find some cut to fit wires but i cant find the right ones... so im thinking lots and lots of heat wrap, but just kinda curious if anyone else has had this happen b4
