Having problems with your 2003 Chevrolet Impala ?

THE CHECK ENGINE LIGHT COMES ON WHEN I PUT IN GAS, NOT EVERY TIME. SEEMS TO STAY ON FOR ANY WHERE FROM A COUPLE OF HOURS TO A COUPLE DAYS, THEN GOES OFF. THE CAR IS A 2003 IMPALA W/JUST OVER 51,000 ACTUAL MILES.

You need to have someone pull the codes and see what the codes are. When your service engine light comes on it will tell the computer something is wrong and set a fault code. After several starts the light will go out because it hasnt detected that same code since the first time although the code will still be set in the computer. You should refill your car without it running as the gas cap works in conjunction with all your evap system and is detecting that you have removed your cap or have a leak in the system. Its hard for me to explain on here but probably wont set if you turn your vehicle off while fueling. When they pull the codes off of your car they can tell what the problem is.
Hi..
well first of all it means that u have a problem some where on the suv the only way to find the problem is to hook a diagnostic computer and see what the code is u will have to take the car to a shop who works on isuzu and im sure they can tell u what code it is and whats wrong or u can take the suv to advance auto parts and they can hook there machine to it for free and tell u the code good luck

OK, the best action now would be to scan the ecu for any trouble codes that may be stored at this point with a diagnostic computer. this action will describe the issue concerning the check engine light and, it will also direct you to the location of the failed sensor that may be damaged at this time.

In most cases, this light will illuminate if a vital sensor has failed to register a signal for a short time or, if the sensor circuit is open.

thank u
