Default Primary 02 Question

Sooooo The turbo had a slight oil leak where the compressor back plate meets the CHRA and long story short it dripped quite a bit of oil on my 02 sensor. Well the oil leak is fixed now as it turned out to just be that ruber gasket in between the backplate and chra was damaged but the problem is that the car will work normally for about the first 5-10 min of driving than will run a SOLID 13.7-13.9 at cruising and runs like shiiiit. Im wondering if the 02 sensor is fubard and it just takes this long for the computer to start reading from it or if it can possibly be ressurected. Any ideas are much appreciated, usually after i let the car cool down for a long period of time, like 2 hrs ish than itll run normal again for about 10 min, otherwise if i turn it off give it only a few minutes than start it again itll run like crap. It runs soo rich at times it wont idle at a light. I havent really pulled the sensor to try to clean it but im thinking of doing that this weekend when i do a couple other things to the car if anyone things it could possily save it.

As a quick addendum, tonight it got really bad and the car wouldnt even run, i unplugged the 02 sensor and at least it would run fine under vacuum than started to freak out a it when hitting boost as i take it when giving it enough throttle to get into boost prob wasnt operating correctly as the sensor not being detected probably through it into a limp mode - but just more info for those who think they may be able to help

It is the sensor. You need to replace it. I had the same thing happen to me but I cruised at 10.5 or lower AFR. I wasted a 1/4 tank of gas in about 24 miles. When I read my CEL it gave it away the problem and a simple replacement fixed everything. Actually my car ran better then ever after that. I am guessing my original front o2 sensor has been sucking the whole time.

Thanks for the link unfortunately i need one locally Think one of these universal 4 wire upstream sensors will work? Shows it will work on the camry which has the same sensor as ours.
