I have a 96 OBDII GSR and my check engine light is giving me code #92, for EVAP imroper purge flow. someone told me it might be the pcv valve that was clogged since my car has 140k but i replaced that, and reset my ecu and after about 5-10 minutes of driving it comes back on. What could it be and how do I fix it. also, I will be converting my car to obdI in a couple of weeks and I was wondering if that will get rid of my check engine light since they have less emissions controls or should I just go ahead and fix it.

oh BTW i'm new here

 

Have you checked your EVAP canister?

 

how do I tell if I need to replace it, how do I check it
