It's called run on and is caused by hot spots in the cyliners. Could be time for new spark plugs or there's carbon build up. It can also happen if you ran the car real hard and then shut it down right away.
What you are talking about is also called "Dieseling" Check and make sure your idle is adjusted. I had this problem with my stock engine when the idle was set to high, I messed with it to get it past emissions and then I had the same problem. Or your throttle could be hanging up a little bit, just a quick tip. But most likely if it presists its carbon build up.
if timing and idle adjustments dont fix it, try using the gm top engine cleaner, i think they call the product Cleens. buy the stuff in the bottle as opposed to an aerosol can. follow the instructions on the bottle and make sure to use it in an open area there will be ALOT of smoke.
the stuff works great, I hear seafoam works well also but I only have experience with the GM product. I grabbed a bottle the other day at the dealer and I think it was about 8 bucks.

I've used the Seafoam product already, it works very well. The instructions I was told are as follows:
1) Pour about 8 oz into a plastic or glass cup.
2) Start the car and let it get up to operating temp.
3) Pull off the brake booster hose and sip the Seafoam out of the cup a little at a time so it doesn't stall the engine right away. When you have just enough left to stall the engine, give it a big drink so it shuts off.
4) Wait about 10 min. before starting. While your waiting you can pour the rest into the tank to continue cleaning.
5) Nose the car into the wind, you don't want to be behind it.
6) Install new plugs if it needs it, sometimes the loose carbon will foul a plug or two.
I've done this to several cars with very good results. I get my Seafoam from the local NAPA store.

Higher octane gas usually stops dieseling too, but is an expensive fix. If all else fails and the car is an automatic, just shut the engine off with the transmission in drive, then shift in to park. This was the only dieseling fix I found for my first high school beater, a '76 Cordoba (LOL!)
