i was told that you must replace all coil packs when you replace one or the one you replace will keep going out! Have anyone else heard this?

Have the fuel injector wires looked at. I had this happen to me before, but it was cylinders 1 and 3. I looked at the the wiring, even all the wire that was factory wrapped and found wires to be broken in half.
