i have a evap not ready and egr not pass. i have had o2 and egr codes that i clear when they popped up every few weeks on my car. now i need to trick the egr and o2 into not coding so that the evap will reset and pass.
i know there is something you can do with a resistor and the o2 wiring but need the how to and figure there is the same you can do for the egr.
