I took my car to autozone when the CEL came on and I got the same code you have. I called my mechanic and he told me to ignore it because many times it is a fluke. That was 3 weeks ago, the light is still on but the car is running OK. Until this morning...but my new problem is seemingly unrelated. I am going to do some intake cleaning this weekend and see if that does the trick...if not I may try the gutting suggestions since I live in the boonedocks where no-ones car could meet emissions!
