When I drive from Palm Springs to Yucca Vally - steep hill - my check engine light comes on when I start back down the hill. The light stays on for 2-3 days then goes off. I took it to mechanic once but the light was off and he couldn't find a problem.

Codes are storded in memory, light doesn't have to be on to retrieve them. Next time it comes on, get it scanned asap, codes will be there. Don't matter if light is not on!
