i have a 97 with a 4.3 and it starts really hard when it cranks it seems to hit a spot where it is hard to turn over and then the engine free spins after a few tries then it starts and idles fine then when u give it gas it starts missing and blowing fuel out the tell pipe. but then i can pull the wire off of plug 4 and the truck starts up fine and is able to maintain a steady idle basically it runs better with a dead cylinder don't know wats wrong checked plug and wires already. I'm on a very limited time table guys so somebody please help any input will be appreciated thanks
