2013 GMC Yukon SLT 5.3L 107,000 miles
at about 90,000 mi or so i changed the plugs and wires (all ACDelco) because it was about time and i had a misfire code show up after i noticed the engine having a slight rough idle for about 5 seconds every 45 secs to 1 minute. its not crazy rough but it is noticable.
i am noticing the rough idle more now and im wondering what it could be and not hoping i will need to replace the engine since these engines are known for the lifters going bad.
i have no issues accelerating at any other speed. the rough idle lasts for a few seconds whether i am in park or in drive.
i have done no mods to the engine except for adding a K&N Blackhawk intake. I did start using Mobil One full synthetic shortly after the tune up. maybe there is some other parts i can replace that you guys can recommend i go with. hopefully @swathdiver can chime in with his wisdom.
Thanks
