Hey, many thanks to the good people here who have
given advice about how to tackle my emissions issue.
A shout out to 83gsIRX-7, Rx-7carl, Solid Snake and S.Shulz for thier helpful insights.
Hey Shulz, your advice in particular piqued me because you claimed you dropped HC's by 400.
That is at the very heart of my problem.
My current readings are HC-444 and CO-2.24.
If I could achieve those same results with ACV tinkering, I would be sitting pretty.
The acceptable limits here in Texas are HC-197 and CO-1.27.
If you or anyone else could elaborate more on the ACV solution in more detail that would be appreciated.
Anything to get HCs under 197.
Thanks again for great site.

 

My ACV instead of blowing enough air to the cat likes to blow it full boat out of the tube that goest out the side and into the carb (larg 7/8 tube). I just took it off the carb side and made that hose go down to the cat air pipe. (I had to rig up a slight extension hose) Make sure yours is blowing out of this tube as mine is and youll be good. Run it really hard before you go in too, it heats up the cat. The proper fix is replacing the ACV, I'll get to that in a couple of years for the next smog check.

 

If your ACV isn't sending the air down to the cat, and instead sends everything to the carb as Steve's does, then his fix should do it for you. But ... IIRC, the ACV is pretty simple. You should check to see if the valve moves. It's probably all gunked up. Clean it off and the ACV should work properly. Then again, Steve's solution looks pretty painless.

 

Indeed. :
