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!
