I asked for the serial numbers for all the modules because you can then see which ones were the original and which ones are replacements. Knowing...
The P3021 freeze frame data shows a 6.44 amp current flow when the code occurred, which is quit low. The lowest battery block was #11 at 14.73V...
I just went back and read what I wrote in post #21. It looks like I made a typo. This is some of what I originally wrote: Block #8 should have...
Static voltage reads for all 28 modules does not tell you very much about the health of those modules. The true test is to look at the voltages of...
Thank you for the picture of the spark plugs and the car mileage. What brand and type of spark plugs are they?
Did you get around to checking the spark plugs? I just looked at the latest 5+ minute data file. I did not see anything to jumped out at me. How...

To diagnose the problem with your car, I would first make sure that I was using a scanner that is capable of communicating with all the ECUs in...
The freeze frame data you posted would be from the P0A80 code, not from the C1310 code. Please post all the freeze frame data, not just some of...
