shudder, smoke, codes...= AOS?

thanks guys - the oil cap was very hard to remove with the car at idle, and when it did come off, it came off with a "ssssssssshhhhhhhuuuuupppp" sucking sound. I removed the aos, few hard to reach bolts, and some almost impossible clips, but it's out.

I'll check out "sunset" today and see how quickly we can get her back on the road.

Thanks again!
