CHEVY FLOODING MOTOR

2004 Chevrolet Monte Carlo

Engine Performance problem
2004 Chevy Monte Carlo 6 cyl Front Wheel Drive Automatic 118000 miles

When I get above 40 mph and I press on the gas the engine seems to flood and sputters. I was wondering what would cause this. The motor is a 3.8 L non-supercharged v-6.

The " check engine" light is an indicator for a system that monitors many electronic functions in the system, also called the " malfunction indicator lamp" (MIL). It can come on for any of hundreds of different causes from any of the systems that the computer monitors. Some are very important and can lead to further component or engine damage and some are emissions related not as serious but still a problem and need to be repaired.

Your first step is to have the computer scanned to retrieve the trouble codes that were set when the check engine light came on. Those codes will give you specific information about what the computer saw and will get you pointed in the right direction to find your problem. With a 1996 or newer and some 95 cars and you have an AutoZone or Advanced auto parts in your area, they will read them for free. Once you have these code numbers, we can be a lot more specific about what your problem may be.
