Your car is running lean and this may damage the engine over time which can get very expensive. As said earlier, the most common causes are a failed MAF or intake air leak. Time to dig in and do some diagnostic work to find the problem. Lots of threads on these codes as it is a fairly common problem on a 10+ yr old car.
