P1055 code help.. Need inspection Bad

Ok so I had a pypes x pipe and some mufflers on my 2005 mustang gt but I needed inspection so I swapped all back to stock exhaust other than the bbk shorty headers for inspection. Well I have a tuner that I got online and set the tune back to stock. I ride to dmv the guy has me turn car off for the test and he reads the p1055 code.. I believe thats something with the o2 sensor right? But what im asking is if theres a quick fix tip out there or how to clear it with my tuner and have it stay cleared just long enough to the dmv wont read it?

Re: P1055 code help.. Need inspection Bad

No quick fix for states that do a visual inspection as well as OBD II. People used to hook up the O2 sensors and just zip tie them up under the car. Most states have caught on and now use a mirror or camera to look up under there. If your're running catless thats an instant fail.
As far as reseting the codes, you still won't pass because the computer has got to perform the checks before being inspected or the system will read "NOT READY".
Sorry I don't have any good news for you, about all you can do is get as close to stock as possible which calls for 4 O2 sensors for a dual exhaust, one in front of each catalytic converter and one behind it.

You can not change the tune and go right to the test, you must drive the car about 50 to 100 miles, a couple heat cycles won't hurt , are you sure about the code could it be P0155 instead?

For the record I fixed the issue. A rather stupid one but the drive side o2 was dangerously close to the headers. I guess the plastic pin broke that holds it tight to the firewall... Anyway the new issue is passing inspection with it coming up that the catalyst and o2 say "not ready"... Is this a cycle thing because I have driven almost 60 miles since the fix and having battery unplugged...

So close, if you were in PA you could just pay to pass. Do you know if DE is private inspection or state run?
