My 06 GT Failed inspection! Tell me why!
I didnt know that your car will fail inspection if you replaced your battery and didn't let the computer reset -
the guy at this local shop told me any car 05 and will fail if the batter has failed or replaced - and if it hasn't been driven at least 30 miles give or take to reset the computer and o2 sensors ect...
is this correct? does this make sense?
06 auto GT - JLT cai - SCT tune by bama chips - long tubes -hi flo cats - slp axle backs - 3:73 gears

Agreed, the guy is right. The OBDII emissions test has two parts: 1) are there issues (CELs, gas cap, etc) and 2) "Rediness" i.e. is the car ready to be tested.
Its this 2nd part that got you. Everytime you reload a Tune or disconnect your battery the car needs to run for a while (somewhere in the 50 mile range) before it will report as Ready for testing.

What you guys are referring to is a Complete Drive Cycle.
Its not based on miles, the miles are a laymans way to simply allow the average person to say "okay I can do that".
Within those 30 miles it's assumed there is mixed driving that allows the car to do all of its checks and run all of the cycles it needs on the sensors. However, lets say you disconnect the battery and drive for 30 or even 100 miles on the freeway without changing your speed. Chances are your car will not complete it's drive cycle and therefore will not be "Ready to Test"
So, in a nutshell, 30-50 miles of MIXED (City/Highway) driving will get the car ready. If you really want the details, get a Haynes manual and look up in the emissions section where it states "Drive Cycle" or emissions readyness. It will make your head spin.
