Thanks for the help, I have looked on a page like that one before and it always says the same thing, "Secondary air injection system incorrect flow" so i do know that much I just dont know what any of that means

Thanks for the help though.

I had the same problem with my 2000. I changed the air cleaner and erased the codes. It doesn't lurch at stops anymore and engine light has not come back on.
