I didnt read this before I posted. Yes it works!

Welp...here I go again with this gd CA Smog check. Failed today.

Last year in February, I failed a smog check, changed the catalytic converter, then retested and passed well within margin.

Then stuck the car in storage. Started it up periodically, but mostly just sitting in storage.

Today, 350 miles and 1 year and 4 months later since the last smog check, I failed.

Im lost as to what to check. The cat only has 350 miles on it since it was changed, so seems highly improbable that its the cat.

Any ideas on what I should be checking to get this to pass?

Actually....that is about to start back up. One upside to this covid mess is its slowing me down enough to start work on that project again. You need to swing by the warehouse and check out whats going on over there.
Just starting to rebuild the LS now....not a full tear down. Just taking the heads off and inspecting to start.
Fuel lines and fuel pump next. Im going to start a thread on this shortly.

But while Im doing that, was hoping to drive this turd a bit.

Your call. I would just non op it and do the change over. If you need stuff, I have a spare EGR, and I have the numbers for the TVS switches and such. The solenoids that run the mess are unobtainium.
