The CEL light came on with no noticable symptoms. Mechanic says the sensor must be changed and the cost will be $500. Seems a bit high, no?

The car was hesitating when I would accelerate. 1st gear was alright, but all other gears would hesitate when I agressivley accelerated. They replaced it and the cR ran great for a week. Then it started stalling and running very rough all the time. Engine systems service light came on. The dealer says I need to replace oil trap and it will cost $770.00. I just spent 1700 a week ago on routine maintanence and replacing everything they recomended, here I am literally 10 days later and the car breaks down.
I replaced the mass air flow sensor a couple month ago. recently the car is idling at the light, starts to shake, and am unable to accelerate past 25mph. Stopped turned car off. restarted and it ran just fine. has done this three time in two days. Always runs just fine after restarting. message center says " Engine system service required" that is a new message I've never seen before
