Hmmm...

I'm starting to think it might actually be misfiring, maybe not crossfiring.

The "hot" part and the muffler part suggests you're dumping unburned cylinder charges into the exhaust and the exhaust eventually gets hot enough to set it off, and you might not be simply firing a cylinder at the wrong time.

This fail could include the sparkplugs, coil, electronic module (obviously not), and possibly the reluctor coil inside the distributor, along with the other items mentioned in my last post. Usually the reluctor will just die at a certain engine temp if a certain type of fail occurs, but I suppose some variations might send a weak signal to the electronic module.

Does it sound like only one cylinder is misfiring, or does it seem like different cylinders are acting up?

Not so sure anymore,
Shoe.
