codes 41 and 42
I have a 1989 Camaro IROC-Z with the 5.7l. The check engine light came on and I scanned the OBD1 and codes 41 and 42 came up. I took the eprom chip out and cleaned it and put back in the ECM and it ran good for about 1 day and the light came back on. Now only code 41 comes up when scanned. I checked the ground and it was fine (at least what I think is the right ground). Then I put die electric grease on the connectors for the ECM to make sure there was no corrosion and that did not help. Does anyone know what else it could be?!?!
