What is the drive cycle for a 2002 Yukon XL 1500

I believe this is a reminder set in the computer and would have to be reset by a dealer or mechanic. I have the same thing happen in my 04 Suburban.

On some vehicles, the computer has to "learn" how to run efficiently after the battery has been disconnected for a period of time. I had an 04 Cadillac that would not idle either after the battery was disconnected for several hours. I tried everything to get it to idle right, resetting the computer, etc. Once I actually drove it around the block it started running correctly after about 1/8 mile. I could not get it to "learn" until I actually drove it, letting it run in park for almost two hours was not enough, it had to go through the process of actually driving to get everything back to normal.

Cars do have a drive cycle to clear up a fault. It more less ensures the issue has been corrected after a certain drive cycle. Some issues have to cycled for 500 miles.

Hello, have you tried to unhook the negative side of the battery for about 10 minutes and then go from there . It should reset the computer completely .

Drive cycles vary by manufacturer. It can be as simple as driving at highways speeds for a certain number of miles, or it can bea number of times the vehicle is started and warmed up, then turned off to cool down. A new car dealership service department may be able to tell you what the drive cycle is for your particular vehicle. Anytime you clear the computer on your vehicle, either by using a scanner, or removing power from the computer, you must go through the designated number of drive cycles to reset the computer diagnostics. It's a lousy system, and the auto industry should be required to conform to some kind of standard for all vehicles, regardless of make and model. But, for now, it's not clear exactly what you need to do to achieve the required drive cycles. If your inspection has expired, keep the documents you received when your vehicle failed the last test, just in case you get pulled over by the police.

it is a lifter sticking till motor gets warm it happens in time i know a trick put i help so much for free.it will be fine try a highmile oil and check it every fill up my be low.

Check the fuel cap!! If the vacuum relief is not working it can impede the fuel flow and cause the engine to shut down or not restart after a stop. Waiting usually gives things a chance to stabalize and the engine will restsrt. When this happens again try loosening the cap and see if the engine will restart.....If it restarts immediately, REPLACE the fuel cap..Do Not leave it loose because this will cause other problems. If it is not the fuel cap the problem may be the filter, the fuel pump, or aome other fuel system malfunction.

bad mass air sensor could be the culprit...it is by the air filter, be sure hose is secure and clamped

The reset button for any instrument display tallies ( fuel consumption, average, trip miles, etc ) is located on the sterring wheel. It should be the button on the lower right with the down and back arrow printed on it. Once you display the item you want to reset, hold this button for a few seconds and the display should reset to 0.

Good Luck

Yup - you may need to get the grilles and such as well...
