Radio Tick

Spec: 1992, 4.0, AW4, 210000 miles

Here is my problem. I just replaced my spark plugs, wireset, cap, and rotor after the change I now have a tick in my radio that changes with engine RPM. I used champion resistor plugs, Bosch wireset and the Wells cap and rotor. Do you think that the ticking is from the performance Bosch wireset? I have check all the connections and they all seem to be good. The speed of the tick is about 3 ticks per second at idle.

A tick is generaly one cyclinder, all 6 wires would be much faster.
The tick is a spark jumping because a wire is not in all the way or you cracked a plug.

It was a bad connection I found it on one of the spark plug ends.
