Thanks for all the info guy's!! I looked last night thru the site for 2 hours looking for that link. I knew I had seen it just, could not remember where.
And yes it was throwing codes. At first it would come on, and in a couple of starts it was gone for weeks. It started about 3 days ago and I can clear it and it comes right back. Car runs fine, it does feel much weaker when I have to give it some gas on expressway.
Looks like a 4 can job, get to know my girl on a more intimate level. She has givin me 70400 trouble free miles.
