1992 corvette misfiring code 13
I recently picked up a 1992 corvette and have done a decent bit of maintenance to get it running better. It runs and drives but is lacking major power. I got it with code 13 and another code for optispark which I cleared already. So far I’ve done the water pump, optispark, spark plugs and wires and it definitely is running a decent bit better than when I got it but it is misfiring and throwing the code 13 for drivers O2 still. It seems like it’s only the drivers side that has an issue which you can feel the difference by putting you hand up to the exhaust on each side. I have tested the voltage on the harness which was .5 volts on both the driver and passenger side as well as replacing the O2 sensor with 2 Bosch ones and now a gm sensor. I got in contact with a mechanic that has worked on lt1s in other cars and told me the ecm is what he believes is the issue. Anyone have an suggestions? I feel like I’m so close to getting this car back to the power it once had and this is the last price of the puzzle. I found another ecm on fb market place and have looked at the mail in ecm repair services and want another opinion before I shell out the money.
