The check engine light only comes on while going up hills? This could be any number of things. Either a sensor or component is failing only under those conditions or something else is effecting the PCM like a slightly plugged exhaust, bad injectors, etc. For issues like this it is cheaper to get a scanner that can read you PCM codes and live data during the issue then you have an idea where to start.
