Question about 2000 Buick LeSabre
I'm trying to pass the emission test but my check engine light keep coming ong when it went out i took it to the emission test and they said it had not reset i need to put so miles on it so how many miles do i need to drive

Unfortunately it is not a certain amount of time or miles that the car needs to be driven.
There are several 'readiness monitors' that basically cover each emissions related system. For instance there is an EVAP monitor that checks the EVAP system and all of it's components under certain specific conditions (No VSS, TPS, O2 sensor, IAT, MAP, Fuel trim, Injector ciruit, EGR pintle position, ECT, or MAF sensor DTC codes set; Start up engine temp 40F-86F; gas tank between 15% and 85% full, Barometer above 75 kPa, system voltage 8V-16V).
So more information is needed as to what failed you the first time. What DTC code was triggered?
If the problem has been fixed right, the history codes will go away after 40 CONSECUTIVE drive cycles WITHOUT the problem re-occurring.

Has the fuel filter been chg. lately. If it has, maybe a fuel pressure test is in order. Fuel pump might be geeting weak and does not show up until it gets warmed up. Fuel pumps are a common problem on this type of cars.

you could go to an auto parts store and they can reset it for you, or you could pull your battery cables off the battery and hold them together for about 10 sec. that will clear any codes.

suspect 'mass air flow' sensor or possibly a rip in the air duct from the air filter to the throttle body. this sensor, if bad, can definitely cause stalling/rough running and is notoriously difficult to diagnose, as an intermittent failure often does not throw a code to trip the chk engine lite. the sensor is located immediately next to the air filter box and has a connector of approx 6-8 wires going into it. one quick and dirty way to elicit a problem (if there is one) is to gently rap on the metal housing of the sensor w/ the handle of a screwdriver or a small light hammer. it is advised to avoid hitting the flat plastic part on the sensor (where the wire connector is inserted) since there is sensitive silicon circuitry underneath and you could potentially break something that may not have been broken already.
