I think it was a year or two ago,it was the obd port that they used and it passed

Good to know if thats the case.

You're allowed one "not ready" in Ontario, IIRC. I expected one for my rear two O2 sensors, but got an EGR instead. Still passed.

Interesting!

Alrighty, update....

Step 2 done. Full insurance coverage is on the GT.

So after loading my custom updated tune with that has the rear O2's turned back on, it pulled a check engine light.
I jacked the car up, pulled the diverside front O2 out, and it looked ok, checked the connector, it too looked ok. As I got thinking... my GT has been running a little rich, and stunk rich after putting the JLT cai in a summer after I had the GT tuned a few years back, but I fully intended to get it retuned with the JLT in place, just never happenned. So moving forward, I made sure the O2 was nice, and tight, and checked the Xpipe at the manifold to make sure it was nice, tight, and sealed. Then I let the GT down, and took out the JLT cai, and re installed the oem factory '01 Bullitt inlet tube, and stock air box with K&N drop in filter since that is how it was tuned. I then cleared the computer, restarted it, and it was crisp, smooth as it could be being cammed, and didn't burn my eyes out, or stink up my close LOL! I managed to get 164 kilometers over the weekend with no check engine light so far. Knock on wood.
Gonna call my buddy at the dealership to book an appointment to etest the GT for sometime by the end of this week this way I can get a few more k's on the GT just incase before hand.
After seeing a check engine light, it makes me paranoid cause I just want to get this done, and over in one shot cause of the limited time I have to fart around with a car.

Stay tuned for step 3, and wish me luck. :)

Great to hear you moving forward.

Good news!

Congrats, seat time = good time.

Have no worries, You are doing all the right things and it's a Mustang. It will pass with flying colours. :tup

After all is said and done you will be happy to get it on the road and let her rip.
