351 issues

[gumby93]

I am having some isses with my 351. I recently changed plugs wires and cap on her and she wont crank unless the throttle is down all the way. so i changed fuel filter and no results. The number 7 wire keeps working its way off the plug as well. I have checked and rechecked all the wires to make sure they are all where they are supposed to be. I am not sure what else to check or even look at. Before i changed tue plugs and wires she ran fine when i drove it home from a friends do to a flat tire. 3 days later is when she was acting up and i discovered the wire came off. I figured good time to change them all. Thats where i am at now. it is beach season and i have no rig to show off. i will gladly check all suggestions i can for as i live in an apartment and wrenching is limited thanx.
