Long story short, car went in to 15mph limp mode. I had her unhook the battery and reset the ECM. she borrowed her uncle's reader, it shows a bad ECM. I ht to coach her through removing the ECM to get the numbers off of it.
I am not there to troubleshoot little issues. So it's a "throw simple parts at it" situation. Luckily the replacement used ECM was $45.
