I have two leaks at the crossover front and collector. I also have the same code and my LFT's are maxed and the 02 at idle sits at 50 and doesnt switch between high and low values. I used no RTV or sealant on my slip joints. Im gonna try some and see what happens. Glad I came across this Ive been trying to figure outis going on. I thought it was a vac leak but coudnt find one
