I keep blowing a fuse for the ecm/tcm on a 2008 Chevy Impala Ss what could be the problem
Check the wiring harness where it goes through the firewall, there have been some problems there of shorted wiring or loss of communication codes that this causes. If you don't find any thing there then disconnect the ECM and replace the blown fuse, if it doesn't blow then the ECM is internally shorted. HTH
did you ever find the problem?? my 06 monte carlo is doing the same thing..
replaced the o2 sensors and engine light still comes on with emission codes and so I checked the fuse box and the emissions fuse was out inserted another and it blew chevy impela 2008
