figured it out. the 135 is passenger side upstream with keys level to eachother. 137 (which is a special order item, but a not-so-local NAPA has 3 of them) is driver side upstream. I'm not touching the downstreams, but I will go ahead and guess those are the 132's.
You've got the part #'s correct. Looks like they sold you the wrong ones for sure.
I don't trust the auto part stores databases. I usually look up the part on the manufacturers site.
Really ought to add the part #'s to the DIY/FYI thread sticky. Or maybe they're in there? It's such a mess, it hurts my eyes to navigate it.
Not sure what is throwing the misfire codes. Hole #3 isn't listed anymore which is progress, but also clouds what is going on. I guess this is where having the DRB would come in handy, be able to exactly pinpoint the misfires on a graph. Granted I still don't understand how the heck it detects misfires.
