you smell gas or exhaust fumes?
Gas - leak as mentioned above - I had an O-ring fail on one of my injectors but that was because when I put them back in when I did my intake manifold swap, it got pinched.
exhaust smell - jack up the car with it running and feel along the exhaust tract for a leak (definitely do it with the engine hot). My thought is maybe one of the header bolts is loose/snapped off and getting the engine hot causes it to expand the exhaust where the bolt is loose/broken (wow that was wordy).

^ could be that too. I would check for leaks first.
