I am trying to get a 240z from a neighbor but my dad won't fork over the dough until the guy gets it through emissions. I was wondering what the failure causes could be and espiecially how to fix them? thanx

Unless the car is visibly or noticably having a problem assume it will pass, take it through the test and if it fails it is easier to diagnose where the problem is. Or you could take it to a shop and have them test it.
