2004 gt 4.6 this is what i have

75mm acufab throttlebody and plenum with a 85mm c&l mafs and intake, steeda non piggy back underdrive pullies, pro 50 shifter and thats all i have installed at this time. gears and headers are not going on until i have my cel problem fixed

everything ran fine for like a month...then i put my basani off road xpipe on, and 10 minutes down the road o2 sensor 2 in bank 2. thats down stream on driver side trips the check engine light...so i plug my diablo tuner in and read the code and thats what it says..ok so i reset it.so i installed the diablo tune to see if that would maybe bump things up a bit to correct it...no go so i returned the tune to the stock one (gas prices suck in ny) .even pulled the battery terminal for ten minutes once to see if i had to do a diffrent type of reset...
still comes on..
any ideas? should i scrap the mass air meter? could that be the problem? or should i need to get a wide band o2 sensor? im car stupid but i did a search on this site before i posted this and all i found was stuff for 5.0 mustangs.

any help or input would be greatly appreciated.

Well with an O/R exhaust you don't have catyletic converters right? If that's he case you will need to get some MIL eliminators or a special chip that sets the code to not ready.

Use your diablo to shut off the rear o2 sensors!!!! that will take car of your problem, you do not need the MIL eliminators as your predator tuner can turn them off!

and in reply to driver thanks dude umm question...where do you go in the diablo to turn them off cuse im not sure where to look.

Can you tell me, by any chance has your car done any chugging or sputtering at about 2200 rpms?

Go under the OBDII section and you wil see the banks listed there, and all you need to do is turn it to off. I believe it is bank one.

nope none..

I'm reading a lot about people having problems with MIL Eliminators failing nearly instantly.

Seems to be frequent with the Steeda's. Like everyone else said, you can shut off the rear O2 sensors via your handheld.
