[V8] car smells bad when running

[Tom Laplante]

Girlfriend say's all my cars "smell bad" and it's just running rich/no  
leaks.  Goes away on warmup, but the parts car(that she drove) smelled  
rich always because of the bad OX sensor......Verify that it's  
smelling out the tailpipe or out of the hood/burning....If it smells  
like spoiled milk, inside the car,  it's the AC condenser, and that  
recirc flap spring may be broken/off.....If it's been sitting and you  
live in an area that the AC get's used, it's "stuff" coming off that  
condenser in the dash, and smells way worse when that spring is broken/ 
mount broken.....Lago smelled like sour milk when I got it.....Tom
