My aveo's accelerator does not respond when going uphill (pumping the gas will work after a delay) and when idling the outside of the car smells like gas, and the engine sounds like it's working really hard. I'm afraid to drive it, and don't know where to take it without getting taken advantage of. I want to know what I'm getting myself into before going to a mechanic. It has never done this before a couple of days ago, and I got the oil changed (it was time anyway) and this did not affect the problem one way or the other.

Just for your info, pumping the throttle on a fuel injected car does absolutely nothing.

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.
