Allegh county emissions - Failed. AHHH

**06stanggt** · 05-11-2007, 11:42 PM

I have an 06 stang GT and have the pleasure living in Alleg. County - I did put more than the 6k in miles on the car last year and need emissions testing. Everything passed but the OBD readiness. I have a C&L CAI and custon tunes from Brenspeed. Well I failed - found out the back o2 sensors are turned off - I replaced the stock air box and stock tune, went back and still failed. Does it take a while for the computer to reset all the diags. and learn? How far to I need to run the car to get all the computer stuff to reset to stock after the reset.

The one mechanic has a stang as said the o2 preheat has to reset first before the other diags will read - I never let the car cool so they probally did not reset. Any of you have the same problems?

Thanks guys!

Nice to see you found the site bud. I could give you a printout of the specific drive cycles for your 06, but like I told you, they are kinda a PIA sometimes. Enjoy the nice weekend and rack a few miles on it, the monitors just need to reset themselves.

when i put my stock ECU back in my GTP and went to get it inspected, it took almost 1000 miles for the o2 sensor checks to run and pass.

Thats odd. My rear o2's on my cobra are also shutoff through my SCT tune. My car passes every year...

Yeah it's me.

Stop down anytime. Only takes a few minutes to check the monitors for ya. Don't worry about John!

This wouldn't be the reason he is having trouble Dan. More than likely the battery was disconnected recently and he did not perform enough drive cycles to reset the monitors the computers needs to pass emissions.

Turning the cat efficiency o2 sensors off(rear ones) in the tune won't affect this.

I have a few of the trouble codes for particular functions that I turn off when I burn tunes for my Cobra.
