I'm having the same problem myself, AM static induced by engine. That means it increases in frequency as the engine speed increases. I unplugged the alternator - no change. Seems ignition is the source. Spark plug wires can cause this also, in my case they look new, yet cheap aftermarket could still be the cause. Bad engine grounds may also be the cause. Some folks have mentioned running a ground wire to the hood, as this is part of the ground plane. I haven't taken the time to chase it down further, but you should know that there's a TSB on this problem. Certain earlier production vehicles made only at certain plants had an issue with a residue left on the antennae and intermediate cable. The fix is to replace them. Check out TSB's on All Data.
