Hi, I have a 2005 cadillac cts and I replaced the ECM and it worked for about a week, then the same issues came back(anti theft icon, temp gauage and gas gauge went out. Took it to the deal did dianostics said bad ECM. The day after the same symptoms appeared. Im wondering if a bad ignition coil could be setting off the ECM and the ant theft. I cant afford another $1230. Any suggestions

Hello. My name is ***** ***** I will be helping you today.

If the symptoms are exactly the same as before and they diagnosed it as a bad ECM that would make this under warranty and not your problem. Why would you want to go replacing parts and give them something to criticize and weasel their way out of warrantying their work?
