massive over filled engine oil

True, I guess it's easily lost in the interpretation as I read it one way way and you/others another - only HAVABEER would really know what's going on.

I know SFA about a 5s-fe so I'm not going to argue either way, but on the 1JZ, 2JZ and 1UZs I've kicked around with for the last 12 years the O2 sensor definately has a huge say in what happens in closed loop under 3500rpm as long as the throttle is not near or at WOT.

Does a 5sfe run an air flow meter? If so, it could also be contaminated - I know on 1UZs in Soarers guys screw them up occasionally with over oiled pod/panel filters.

yah the have an AFM and the EGR is plumbed back to the intake/inlet hoses. Try cleaning thoe out/checking them. And yeah, i meant carby clean- brain fart

My 1st st162 (3sge) had a rooted 02 sensor the whole time i had it. Idled fine and ran fine just hell rich when gunning it. 5s shoud bethe sma - it probs wouldnt hurt to check it though

Is the CAT part of your headers. On my 1998 5SFE It is. If so it my have dumped a fair bit of oil in there.

cat isn't part of the headers/manifold, theres a flexible flange but i doubt there's oil in there as it would have burnt off by now and as there's no more smoke coming out.

thanks though
