the first one iv had no luck figureing it out. but the 2nd one is really a loss of ideas on how to go about fixing it. i have installed 3 diffrent o2 sensors and i get the same code. only hting i can come up with is that the o2 sensor isnt reading properly or something cus of its locaton, its now located directly in the turbo turn down directly accorss form the exhasut turbine. this puts it a good 4" maybe more from any thing. so maybe its just tossing it off being so far awya. like when you got to a larger ehxuast system sometims your senors flip out due to the highter flow and the sensor being spaced out further than normal creating havic w/ the senros working how it "thinks" it should. but this is all soemthing iv fabrocated in my onw mind and im proably worng. ug...... why the fuck amd i geting this o2 code?......... and why dont i have any pants on?..... ahahah

thanks

any ideas are help
