i have a 99 150 4.6 v8.....the truck does fine when i crank it and runs great for a while.it seems like when it gets warmed up good it starts to sputter.every now and then it jerks like it has a dead miss in it,......anyone ever have this problem?what do i do to fix it?

 

when is the last time the coils / plug wires were replaced?

 

I had the same problem and changed plug wires,now it runs great.

 

i changed them about 2 months ago
