will you still get check engine light after you install mill

you mean with working 02's? MILS make sure teh CEL doesnt come on

you have four sensor. right and left bank. 2 on you manifold and 2 behind our cats. Your either running too lean or rich. Are you running a tune or doing it yourself. If your running a or pipe and havn'tconnected the mill conectors, o2 sensors will keep tripping your engine light. If you have a tuner , you can shut your rears off. If your still tripping them and all is done as I mentioned, it's time to replace your front o2's. The code should say one of your banks are running lean or too rich. You could also have a faulty MIL. ALso, if you get new o2 sensors, do not by aftermarket. BUy ford o2 period. I learned the hard way & found out the aftermarket I bought at actionauto from Boush are junk. I returned them because they kept throwing lean bank codes. I havn't had a issue sence w/ the stock ford o2's/. Plan on spending $90 a piece. I run the same set/up as you.
