PCM 1431 code
Just went and looked at my codes on my DIC, on my 2001 Vette, a PCM 1431 popped up, along with about 6 others (will write them down later).
From what I can ascertain it’s something about the fuel level. The first night I brought it hone the fuel level dropped to E but hasn’t done it since. I’ve been putting Techron Fuel System Cleaner in it.
I’m thinking I might disconnect the battery for a while, and then drive it for a few days and see if it comes back. Any advice on this? Thanks

Welcome to the CF! I used to get all my stuff from Bedford Tack, in my Walking Horse Days. Went to many Celebrations.
Marc at Vettenuts is close to you. He is a regular vendor here.
When you get your Codes, there is a letter prefix that will give a clue as to the system. Also there will be one or two suffix letters, either H or C, which stand for History or Current. Sometimes you will see both H and C at the same time.
These codes technically called DTC’s. Many people use these codes to decide which part(s) to replace. This is not their purpose. Consider yourself lucky to buy that correct part that resolves a DTC.
