There should be a 3 or 4 letter code on the PROM, what is it? If stock it is on the silver label.

frh thanks

FRH is correct for an '85 Firebird with the 2.8l engine. It is FED emissions, with the 700R4 transmission (automatic), and manually controlled A/C system.

thanks for your help uh does would it be worth replacing the 6870 with the later model 7302
from rock auto

The ECM won't come with a PROM and the '6870 PROM won't work in the '7302 ECM. I don't know if the '7302 ECM is any better, although it likely does has better firmware.
