CaddyPhil Posted August 28, 2015 Report Share Posted August 28, 2015 My 1996 Deville has the engine light on and will not pass emissions. My dad's car, he thinks its a bad ground? The repair shop wants to replace the PCM at a cost of $502 pluss around $300 for installation and programming. I found one on Ebay for $89.95 programmed. Anyone familiar with this issue? Please help.. Phil Quote Link to comment Share on other sites More sharing options...
