Well I am back drivable again. I changed the down stream O2 sensors. Rented the sockets from AutoZone and yes the torch helped. Also changed the fuel pressure regulator the same day So the combination of the two? Or one or the other got me going? Brought the car/truck to Monro muffler (a muffler brake chain on the East Coast) to have the cats tested. Or at least I thought…? They said they never hard of such a test... ie Testing pressure… Drilling holes, or going through the O2 entry? I think they banged on it and said it don't sound clogged. But that they could change the upstream sensors for $175 said they would drop the drivetrain to get at them better or something. So as of now she seems to run fine again unless I'm going up Steephill or really romp on it. The CEL blinks then stays on and I throw the p0300 code (multi-misfire). I did change all of the plugs, so next up I'll be checking the fuel injectors, coil packs and intake manifold gasket for leaks etc.
