[BFix] SMOG Test

[STEPHEN NANCY GEORGE]

Here's a few things you can try. Unhook the vacuum off the EGR valve and apply vacuum to the port, if the valve is working the engine should run rough/die due to the EGR pintle being opened up. You can also hook up a vacuum gauge to the vacuum going to the EGR valve and see if vacuum is being applied to the EGR valve when you are driving at highway speeds. You can also leave everything hooked up and apply power to the control solenoid and see if it applies vacuum to the EGR valve. HTH Steve G.

To keep this political and on topic I just failed my CA government mandated SMOG test this morning. 
 
I have to go to a SMOG "only" station and they are forbidden to do anything but test the car. So I can't get much meaningful advise from them.
 
I have a 90-93 Stang 5.0 SEFI AOD setup in my 77. I failed the NO (ppm) test with 1078 (1015 max pass) @ 15mph and 1047 (875 max pass)@25mph. Last time I had it tested 2 years ago I also failed the NO and installed a new EGR and new Cat and passed.
 
How can I test the EGR system. to see if it is working correctly?
 
The cat I installed was a cheep catco from Summit, about $65. I have heard since that the catco cats are really junk and will only get you through one inspection. Anybody have any insight into this?
 
Thanks
Norm
