emissions passed!!
Took the Vette to emissions for its second go-around after the mods; it failed earlier this year with HC *way* over the limit. After that, I had found that the hose on the AIR system to the cat had gotten a crimp, so I put a molded curved one in place. I also added a second PCV valve on the pass. side to try and eliminate some overpressure. Finally, and this may or may not have been needed but I REALLY wanted to pass, I dumped a bottle of 94% iso alcohol into 3/4 tank of gas.
This time, passed with flying colors. Not even close to the limits. Woohoo! Two more years of massive mods!

Congrats Rich. I know what it's like to sweat out an inspection. Mine is coming up in January and with this idle issue I'm getting concerned even though I passed last year by a wide margin as well. I sure would like a 2 year cycle instead of every year.......

Same lane, believe it or not...
Track times in the spring, after I spend the winter tuning with the PROMinator that should arrive any day. I did do a 13.71 @ 105.84 in 95-degree weather last June.

Yup, I am quite happy here... now just waiting for the Prominator to arrive so I can start dialing things in.
Found one problem with my custom prom - it thinks I'm driving an automatic! That'd make the ol' OD run oddly  .

Congratulations, Rich.
Unfortunately, this is something that I'll have to deal with next year. Or maybe I won't...
But I don't think I'll have a problem since I'm going to do extensive work to it this winter. My plan is to have it running faster with better gas mileage and lower emissions.

Sounds like a good combo... let GM in on the secret when you figure it out .

Congrats, Rich. I know the relief, but may face all that uncertainty again if and when the 406 gets redone.

By double headache, you mean that the inspection is visual and running the car on the rollers, right?
That would be such a pain!
Rich, why up so early on a Saturday morning?
