Seriously! Take the car for a drive in the country.
It has to go threw a few drive cycles (Ign On and Off miles at particular speeds, cooling fan has to cycle a certain number of time etc etc...)If you live by a turnpike take it for a spin.

What is the drive cycle or vehicle break in for 1999 Malibu After I changed the battery last week, I went to inspection today and failed

There isnt any drive cycle or break-in for a battery being changed out. You will need to take your fail slip to a service shop and see what caused the vehicle to fail inspection.

2006 uplander replaced battery month ago then replaced again yesterday cuz it was leaking now new battery is leaking and car has a misfire code

check your alternator.if it is overcharging it can cause the battery to leak. IT should be built into the alternator, however if it is not have the voltage regulator checked as well. After you do this reset your computer and if the cylinder misfire code returns you will need to inspect your plug and coilpack/wire.

My 03 Focus has failed emissions 5 times now...same codes as always. It's failed every year, and ive reset and driven and passed. now, fail.

By failed Emmissions you mean it failed inspection? If this is the case you got some bad gas somewhere. If you ever had the vehicle in Europe then you most likely will need to have the exhaust system replaced as they test from the tail pipe. This could also be the Catylitic converter. If you are talking about the check engine light going off it is most likely an O2 Sensor that needs replaced.

I have a problem with my 2001 Toyota sienna, took it to inspection yesterday to get inspected and didn't pass results Cat not ready and evap not ready, inspector tell us run the car couple miles and bring...

If the "evap not ready" readiness monitor never clears and you keep getting P0440,P0441,P0446 type codes, then you have a problem with the evap system. You have already tried the gas cap (good start) but there are about 6 other things it can be from electrical VSV air valves (there are 3 of them, 2 under the hood, 1 near the charcoal cannister (behind fuel tank) to 2 air operated valves on the front of the same cannister. There is also an air line that goes to one of the electric VSV valves on the air cleaner under the hood. Several oil change places have been guilty of pullling these off and not reconnecting them.

Oxygen Sensor

if you had it replaced it should have already been set however you can reset your cars computer by taking the positive battery cable off the battery and waiting 2-3 min and then touching the positive cable from the car to the negative cable which is still attached to the neg post on the battery for about 5 sec and the hooking it back up. that will reset the computer which would configure any new sensors. when the computer reads a bad code it bypasses that sensor so your car will run. it wont run to the best of its ability though - that's why you didn't pass an inspection. when you replaced the sensor the computer didn't notice because it already stopped reading that sensor when it went bad and doesnt know about the new one. when you reset the computer as i told you then it will read the new sensor and work properly.
