You are the best!!!

Turns out it was the exhaust, but it was that the shop that fixed the cracks in the manifold and downpipes didn't fully tighten the O2 sensors.

All four, which I replaced prior to realizing I had exhaust leaks were barely hand tight. Got them all snugged up. Now I need to put some miles on this rig to get the P0134 error to go away since I just changed the battery as well.


Thanks everyone!
