Non Mopar related, but could be used to help Mopars too.
2004 Ford Ranger, 3.0 V6, auto. Stock non pioneer Ford radio. I am experiencing ignition noise especially at idle. If I tune it to a frequency where there's no station, it's pretty loud. It is also very noticeable on somewhat weaker stations.
It is not "one", it is all six. After I did the heads this last time, I added new NGK plugs and wires. Gapped the plugs to factory spec. All the wires are routed away from manifolds and through the stock wire looms and clips.
There are no broken wires and no sparks that I can see at night under the hood. The truck does not skip and runs flawlessly. No codes or pending codes in the computer.
Here is the possible culprit. The only thing not stock on the ignition is an MSD coil pack. I put that on with the plugs and wires. It is hotter than stock. By a good bit according to MSD. I got it because it was about the same price as a stock coil.
Is the coil possibly the culprit, or should I look elsewhere? What other possibilities could be causing this? I double checked all of the grounds and they are all hooked up from when I did the heads and all clean and tight.
Any insight is greatly appreciated.
