Help P0601 2005 C6

[Ryskin7]

Hello everyone, I made a thread a little while ago and have done lots of research on this common electrical gremlins in the C6, 2005 especially… my 05 2 drives ago which was about 2 months ago now went into limp mode while driving around 80km/h engine light came on, reduced engine power, and power steering lost.
I ended up disconnecting my battery and re connecting and drove home with no issues. Then after research I tried to clean ECU connectors and check some grounds in engine bay all seemed good, a week later I went to take it out and it stalled out about 10 mins of idling , well at that point I put it into the garage and left it until last night I was thinking about it and doing some more research and very briefly I caught someone say check for loose battery terminals … so I did and they were very loose both + & - like I could turn them left and right and take them off with my pinky … i tightened them up temporarily because I think I need new terminals and I took my car to get gas and I had it running constantly for about 35 mins with no issues ..

I did end up buying a used ECU to have my shop put in and re program but I really want to get to the bottom of this … could anyone please share their thoughts and suggestions on what I could do ?

would loose battery terminals cause the issues I had or is there more going on than that and should I continue to have my ECU replaced ?

thank you I look forward to your guys suggestions

How is it starting? If it was the battery, then you'd see issues trying to start it as that is the largest power hit to the battery.

seems to be running perfect but then randomly it would stall or lose power while driving

Except yesterday when it ran for 35 mins no issues… do we think that the battery terminals would cause this internal ecu issue though? Not sure

I don't see how, really, but you never know. I'd think, like any computer, Internal memory checksum error would mean some bad memory. Close to failing. You could have your ecu reprogrammed to see if that fixes the issue before actually replacing it. That would be a long shot though. It might be having problems reading the tables.
