So just bout this and I have an N/A setup I'm just wondering what I do with the small vac line that was on the combo valve as right now I just have it sitting there but..... Basically I have everything off that the guy on page one for the quick DIY has off just curious about that vac line?? Thanks

Just wondering what a resistor at the pump connector will do to stop p0411 sec. air incorrect flow codes? You may not get a code for the pump itself being open but the O2 sensors will not read any change when the pump is "turned on" which causes the ECU to "know" the pump is not flowing air into the exhaust. This is normally how the car monitors either a broken hose/ stuck combi valve/ a pump thats just not up to snuff, etc. I dont see how a resistor at the pump connector stops that code (and po412 which I believe is the code for bank two)? As far as I know a software tweak in the ECU is the only way to completely remove the sec. air system and not get a check engine light.....could be wrong tho
Also, I will be ordering this piece soon as well, I already have the UM flash
