Hi all, my name is Carman Hammond and I just bought a 2003 EXL with just over 300k Miles. It was well maintained with lots of records. However, it is showing an EGR code from check engine light. Also have the VTM light on. The car stinks really bad from exhaust when it’s just sitting running and I want to correct this. I have researched how to change out the valve but should I be looking at other things as well? Thanks!
