    Thanks again you guys!
    Might have been corrosion at the data link connector that finally got knocked loose after plugging the scan tools in and out several times.

    Glad you got it all sorted out. If you had a big vacuum leak (the line to the PCV is a big one), it could take out the O2 sensors over time. The car must run a lot better now.

    Yeah me too! Yes it was a big vacuum leak as I was able to hear it - but could never find it. Come to think of it it was leaking for a while and is taking out the O2 sensors and they do need replacing now.

    Oh yeah... BIG difference in acceleration too - I can actually burn off the line without the hesitation now no more chugging off the line upon full throttle!
