2004 V6 electrical issues
So on 2 separate occasions now I've randomly blown fuses. First time was the HEGO/transmission fuse. Turned out to be a wire touching something. Finally got the fuse to stop blowing immediately upon turning the key. Now all the sudden the PCM fuse blew. My first suspect would be a ground or a short. However, I heard rumbles of bad coil packs causing issues in other electrical systems. Any tips would be appreciated.

If you have a 2004 with a V6, you have a 2004 Heritage which is essentially a 2003 model truck. You may have better luck in that section.
