Yes, it's a '96 LT1. No, no other codes thrown. I had been having what I thought was an electrical problem, but it appears to have been a bad fuel pump. The car never stumbled or coughed when the engine light came on.
I replaced the fuel pump last weekend and the code showed up last night. I had never had that code show up before and after clearing last night, it hasn't come back up. I've put about 30 miles on the car since last night (daily driver).
