2016 Yukon 5.3 4wd 173k miles
Bear with me as I am in no way knowledgeable when it comes to vehicles. My Yukon just had all spark plugs replaced, I do tow with it. About two weeks ago it does this thing when shifting from 2-3 where the rpm jumps high, vehicle lurches forward then temporarily looses power then is fine again...- brieezy85
