Intermittent loss of voltage Today, I started the car in the garage and let it idle while scanning and monitoring voltage, and it died while idling. This is a 2005 GTO, E40.
In the scan, I let it idle and blipped the throttle a few times and at frame 3186, the voltage drops to 0 and dies. I did not turn off the key, but just restarted. At 3238, the voltage is 12v and drops to 9.5 v by 3239. At 3245, I am cranking and the voltage is 10.5. It doesn't get back to 12v until 3278 while it is running.
I don't find any loose connections. Is there a resistor in the power wire to the computer??
The battery is only about 6 months old.
The car will die when driving also, but if it is in lockup, I can just put my foot down on the throttle a bit and it keeps going.
I have attached the log and cfg.
Thanks for any ideas.
