Yes i was saying external sorry for the confusion, I'm not always the best at getting across what I mean. I haven't done a compression test yet but I've never had any smoke a wot or decel so I think my rings are still ok.

I data logged it again and watched it this time, drivers o2(bad one) never got above 120mv and bascially never moved from 100~ where as the passenger side would go from 1 to 950mv. I'm going switch them shortly and then datalog it again. If it follows it, should be a easy fix cause the o2s bad. If it doesn't follow it that means I have a lose or broken wire somewhere?

The car runs fine in open loop, runs like shit in closed loop for like 10 seconds and then goes back into open loop.

Again, thanks for all your help guys, means a lot to a newbie!
