thanks guys, i figured i start at idle before anything else, also my driver side cat is pretty much gutted and passenger is not and i noticed that the long term on bank 1 was 8 and bank 2 was -1.5 is the converter causing this and i need to put another converter on thanks, i hit a rock one day and it knocked it apart thanks

I don't know what you need help with exactly, but it sounds like you have either bad O2's or a huge vacuum leak if your LTRIMS are both maxxed out at 25% on each side. You need to get that cat fixed or removed too.
