Revealing mistake: You can see naked fitness guy breathe while he's lying on the morgue table.

Dead Ringer - S4-E20
Revealing mistake: At the beginning of the episode, when Grissom notices the body and pulls over, in the close up of him you can see that the steering wheel never moves: he just moves his hand to make it look like he's pulling over.
Getting Off - S4-E16
Continuity mistake: When Jamal is been helped out of Ed Burnell's wrecked BMW 7 Series, the wrecked car is a late 80s-early 90s E32 model. However when Burnell was driving it at the beginning of the episode, it was a newer late 90s-early 00s E38 model. Again, the production crew couldn't afford to wreck a brand new car so an older one was substituted.
Other mistake: When Grissom's vehicle is shown driving to Jackpot, Nevada, he is shown to be driving on the wrong side of the road. (00:03:15)
Revealing mistake: Dead antiepileptic guy is breathing while on the examining table.
