1994 Corvette H41 code
Ok last year I go into the garage start up my 94 and the second I put her in drive she cuts off won't start.
I put in a new ignition control module and she runs, but I get a code H41 bad ignition module ground. it's not on all the time it is sporadic sometimes coming on when I let off the gas and off when cruising.
I took it to a local american car only shop, I did not tell them about the new ig mod. they said it could need a new one of those or maybe a new ecm which a dealer would have to determine.
Well now my emissions are due and I need/want this light off without going to the dealer.
Any idea's?

Have you ever cleared the codes. You can use the onboard diagnostics or remove the battery cable for 30 seconds. I would at least start there.
Then I might clean all connections at the ICM including the ground.
I might also clean the connector at the PCM that relates to the ICM connections.
AT some point check for codes and see if it reappears
