Do the DOHC ZC's that bolt up into the 88-91 civic/crx's come with an egr valve?

 

No. The Japanese where never very fond of EGR's and their emissions laws were loose enough back then to not need them.

 

just cehcking.cauase i know if i go for my emmissions test i will fail for high NOX. I already tried retarding my distributor but i think i might have to look some place else.....

 

If your cat converter is good, it should pass the NOx test just fine. :dunno:

 

I agree

 

cat is functioning but i dont think to the fullest affect.because my hcs are kinda high during driving test still......my stock dx engine which i had before used to burn oil.so i think it jus fouled the converter.ill be getting a new cat soon anywayz
