Slow start up

Asked by GuruBBQJ4 Dec 26, 2018 at 06:14 PM about the 2002 GMC Yukon SLE 4WD

Question type: Maintenance & Repair

My 2002 Yukon used to fire up as soon as I turned on the ignition.  After 132000 mile when it's cold, it take a few seconds to fire up.  Would cleaning the throttle body correct this situation?

Yes that would help but also check and replace air filter if needed add fuel injector cleaner to gas tank and change fuel filter if have not done so in awhile.
