Penguin, read that article actually in my search. But I don't want to spend the money if that isn't the fix, SFCL gave me some good hints to look for, and I did some more digging and found someone who had a similar issue, and he found it to be 2 cracks in the rubber air boot i think between air flow meter and throttle body? Now I just need to figure out where this is located and also how do you check for vacuum leaks in vacuum lines???
