I recently bought a 99 600 f4 ran great till a week ago it wouldnt fire it would crank but no fire i put it in the shop and they said lose spark plug wires and fixed it, a few days ago it happend again i reached down wiggled the out side wire on right and it fired right up any ideas on what may cause this? bad wire harness or connectors maybe?

 

If the shop "fixed" it, then take it back & tell them to fix it right.

 

I thought about that but i don't have the money to let them tear it down and see what's wrong. I wad hopeing some one could point me in a direction in what might cause it to happen, what would make a wire come lose over a short time or maybe a short and. A wiggle gives conection again

 

Well if you really dont want to deal with that than you could just replace it all

You are missing the point...

If the shop said they "fixed it" & its still no fixed, then take it back to them & have them actually fix it. Its on them to cover the cost, not you.

 

If the plug wires are loose on the plugs,(remove a plug and see if they actually kinda snap on the metal end) you could give a light squeeze with a pair of pliers and that will close the metal plug end so it will be good and tight on the plug. They will loosen up after time, but should still make contact. Like the other posts say, you paid the dealer once, now they should fix it at no cost!
