Default 88 CRX Failed Smog!

Help! My stock CRX DX failed smog even after a replcement cat and o2 sensor! Someone has mentioned a "purge kit" that would replace the injector-anyone heard of this or have any suggestions?? Thanks!

if its an si or dx try getting an hf ecu and running it on that, it'll run alot leaner, with much less power, that is what i do when i have to smog my zc

I would have thought running an HF ECU would shoot the NOx readings through the roof, because it was too lean.

Besides, a DPFI motor would freak out with an MPFI ECU.

well i dont know about the dpfi dx but as far as zc's and si's an hf ecu is priceless on passing emissions. that is what i have done for years.
