Well guys, my 2002 Ex V6 Sedan is making me think it'll finally kill me on the drive to work with some carbon monoxide. It's around 192k, and the smell has been getting progressively worse, from it being questionable that its happening at all, to happening occasionally. I of course want to get this thing fixed, whether it's a leak or something else. I've done a basic look earlier today since the winter freeze seemingly ended today, but couldn't find any visible leaks. The smell only appears while moving and the engine is under heavier RPM loads. The smell does pass, but I'm still not sure what could cause something so inconsistent.
