First time posting to the site. Lots of good helpful information here.

2013 3.5L Lariat Screw 152K miles

Trying to decide if I need to do the timing chain replacement job. Truck idle is erratic and feels like it lacks power and/or misses/cuts out when under hard acceleration. Has new plugs, all MAP sensors cleaned, new throttle body, KAM reset. I do occasionally hear the cold start rattle, but only once every 3 to 4 months. Just not sure if timing chain could cause the symptoms I'm experiencing. I'm just a little surprised I haven't had more cold start issues with the mileage I have on the truck. Thoughts please.
