Denalis are famous for clogged fuel filters. Change the fuel filter first and see what happens, Get the code for the check engine light. It could be you have a clogged EGR ports. Remove EGR valve and clean out the ports, replace with new gasket and see what happens. Advise of results.

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.

jeeze, so many "common" causes. but THE most likely cause is an oxygen sensor out of range. replacing same and driving several miles might get you lucky and save some money. but note, a restricted fuel or air filter will likewise make this sensor report bad data and set the same code. in other words, don't ignore maintenance issues...

What is the drive cycle for a 2002 Yukon XL 1500


I don't understand "drive cycle". You can clear the codes by unhooking the battery for 5 minutes then repowering.

Check engine light has come back for the second time after having change the air filter and resetting. Now receiving a code: P0101 What do I do now?


Probably carbon build up on a sensor. Had this happen on a Ford Expedition. I put it on the highway and hammered it several times. It blew the carbon off the sensor. Light went away.
