4k miss fire/over fule

[stx-16]

well it is a 4k shift kitted auto (i know its a 4k and auto i know its shit)
the other day i found a huge gravel pit so i done a few loops and stuff about 40mins after that it wouldent let me get passed 110kmph or about 80 going up hill and sounds like its over fueling or miss fireing and it sort of jerks and pulls back a lil bit

can some one please help me

spark plugs, rotor cap/button, points, leads. check all that in that order and i'm sure you'll find something wrong.
