Also I included some picutres of the 2 spark plugs I pulled. They look rusty. But I think that might be due to Chevron Techtron fuel additive that I used. The gap is about .038" - which is good.
Okay my friend, I even broke out the good headphones for this one.
I am sorry to give you bad news, but that sounds 100% like a bad rod bearing to me. The resistance from the added friction could also explain your 'quick deceleration' and low engine idle speed.
I really-really would love to be proven wrong, but as far as I can tell, it's certain.
Not sure what your budget would be in this case, but it
does make a good argument for swapping a V8 into place! Not sure what a repair would look like, cost-wise.
