Question cold engine revving

Hey everyone I was wondering if I could get some opinions on what could be wrong with my truck. Hers the problem if I start my truck only when its cooled down completely it starts to rev up to im guessing 2500 rpm and and comes back down to a normal idle then randomly surges back up then down on its own until it warms up completely. It still does this even in drive until completely warmed up. Heres a list of parts ive already.replaced iac twice cleaned tb replaced tps and checked wires with a dmm replaced converter with magnaflow direct fit replaced rear o2 replaced pcv valve and hose. Once its up to operating temp it runs great besides having slop in the timing chain double roller will be coming soon just waiting on $$ sorry for the long post im just at my wits end thanx in advance!!
