After indepth diagnosis my 13 years old ECU had gone bad. The ADC in the ECU was missing reading sensor voltages, minor signs started 1.5 years ago until the car could only be driven with scanner assist and code deletion. The higher the temperature under the hood the more DTC would appear. A new ECU purchased from Mintt was supposed to be play and play. No such thing! Programming issues existed between the ECU and BCM requiring me to get the replacement ECU to be reprogrammed with the old ECU operating system. After 7 hours of technican work the car runs like new. They say rarely do ECUs go bad, in my case yes. 187,000 miles and good to run again!
