ok lets see i have installed o2 sensor simms with extensions in the place of where they went since i have an off road y but the dang check engine light comes on and off and on and off just whenever it pleases. Someone said you can have the rears deleted with software but i know zero about that. Do you think it could be part of the problem with performance? I have stated on here several times that before headers i dynoed at 315 after i made 312 either way after i get the ls6 intake on and the cam in i will get a professional tune so maybe they can fix it then but if it is something needing fixing now i will get it done now
