Question about a 1985 C4 RPO Code
So in decoding the RPO codes in my newly acquired C4, I noticed one code that I was not expecting, the NN5 code, which stands for California emission package. Is this on every '85 C4 or just the ones shipped to Cali? Also, what would the California emission package make different on my car VS one that was not shipped to cali?
Thanks!
Thanks!

Years ago I believe I documented that but I didn't bother today to check it any further.
I don't recall there even being different PROM calibrations for '85 BUT again I didn't check today.

No if that RPO code wasn't on a car presented for a Cali "warranty repair" then there wouldn't have been the extended coverage and the repair wouldn't have been covered. The Cali regulations at the time covering warranties I'm quite sure only applied to cars "sold" in Cali and no others.
