so guys in continuation of my current problem my car will drive perfectly fine up until it gets hot then it will sputter and eventually die out i can let it sit until it cools and it drives fine again until hot, its throwing code 42 and when it stalls i see that the battery voltage is below 8 volts but when i fire it back up voltage goes back to normal, is this in anyway associated? i know someone told me a bad icm has similiar symptoms?

 

im thinking its the ignition module having that it only happens when it in running temp how can you test the icm?
