I have a fancy diagnostic machine thingy...okay, that didn't sound like I know what I'm talking about. MY HUSBAND has a fancy diagnostic thingy machine (costs like 7k)....my CEL is the freaking EGR that I JUST replaced with a brand new one a few months ago. We just completely disconnected that stupid thing until we have time to deal with it...so I guess I get to look at that CEL for a little while. Out of the 7 vehicles we have, the VX was the only one without that light on, until now
