If you have a cel on your mustang after you installed after market headers exhaust etc.. you probably need this part AutoTube.net Home of the anti fouler o2 sensor simulator !

O2 sims will only work on the 2005-2006. They won't work with the PCMs on 2007 or later.

No, if you install aftermarket headers or an intake and get a check engine light then you need to either buy a tuner with custom tunes designed for your car and your new mods, or go get a custom dyno tune.

All that Autotube thing does is turn off the light, it doesn't fix the problem that made the light come on... :/

HI,

I have 2 '05 V-6 Mustangs, both with 20k on them. I'm getting check engine lights on both. The one I had scanned. It was for both O2 sensors bad. I haven't had the other one scanned yet. The cars are basically stock, with the exception of AEM brute force air intakes on each. I did replace the AEM filters, with AMSOIL powersports filters. Other than having both cars with all AMSOIL products in them (crancase, tranny, and diff), there are no other aftermarket products installed. I looked up the one on Ford.com for recalls, and it shows none. I know the gas filler problem wasn't a recall, but a TSB. Does anyone know if there are any TSB's on O2 sensors? Any idea why I'm getting these codes? With the MAP sensor 'downstream' of the air filter, there would be no reason for the air filters to be the cause, right? I was thinking that maybe the car was getting 'too much' air? Can that happen? Any ideas will be appreciated. Thanks, John
