Why would I be smelling exhaust fumes in the car with windows shut?
There are no apparent exhaust leaks but if there is a small one how can i find it? Is there anything i can look for?

I had the same smell off and on since I bought the car a year ago... at the same time, I wasn't able to pass our California Smog test.
Just last month, it was determined that the down pipe(exhaust manifold pipe?) between the engin and the catalytic converter had a crack in it. The pipe was replaced. The smell is gone and my car finally passed smog!
I can see how that pipe could be cracked by hitting speed bump or dips and such over time... The car used to sound noisy like you can hear the puff puff puff sound from the engin probably through the crack in the pipe. Now it's ALOT more quiet.
Good luck.

The smell from an exhaust leak can be mistaken for fuel. It is probably comming in from the fresh air intake. Set your heater control to recirc and see if that makes a diffirence. The best way to find a small exhaust leak is to have someone hold a rag over the tail pipe to build up pressure on the system and listen for a whistle.
Good luck.
