I have a 2005 Chevy Impala and the check engine light just came on what should I do?

Take it to a place like Auto Zone and they will hook up their computer to it and tell you what the fault code is for free. Most common is a misfire which would indicate new plugs or wires.

What does it mean when the check engine light comes on

It means that there is a problem with the engine emission controls. A special Code Reader is required to find the problem. If you have an Advance Auto, Pep Boys or Auto Zone in your area, they will be glad to check it for free. Some Parts Stores also.

How can i reset de computer of the impala?

i am guessing that you want to reset a code or shut off the check eng light.
if it is a newer model impala like 1997 or newer, you have the new style OBD set up, easiest thing to do is take the car to an auto zone or advanced auto and they will reset your computer for FREE with a handheld device that communicates with the cars computer.

I have a 2001 grand marquis...and the engine light is staying runs great.I took it to auto zone to get it tested and he looked at the code and said it has something to do with my gas.It has been on...

Try getting gas
tighten the cap till it clicks
Take it to auto zone, have him clear the error codes
And see if it comes back.
A common code for all cars is vacume loss in the fuel system, or loose gas cap.
Try it.
