My neighbor just bought a really clean '96 Sub 2wd 5.7, 165k well main't highway miles and the check engine lite is on. It's code >>> p0420 and p0430 catalysts efficiency low bank 1 and 2. That's the REAR sensors, after the converters.
The local Goodyear disaster said it's the converters, and the 02 sensors are OK. That's where I came in. My neighbor was heating up the manifold studs with a propane torch. I made him take it down off the jacks, and to the FLAP, and that's where we got the codes.
The Bosch sensors there are $60 each, and eBay has Borg Warner for $33 shipped.
A friend works in the emissions business, but hundreds of miles away. He says the converters should be OK, even tho the Goodyear shop rapped on them, and they rattled. I didn't hear any rattle, and it runs fine. We also changed the PCV valve, and carefully checked for vacum leaks.
I'd have taken a pix, but I have trouble with 2wd TEERUKS... Lol...
